What are the digits in the number?

The number of integers in a number is called its digits. A number is said to be a single-digit number when it is between 0 and 9. Hence, the number is said to be a 4-digit number when it is between the range of 1000 and 9999. In c programming, we can print the first and last digit from the number with the help of a small program.

Algorithm:-

1. Declaring the variables for the program.

2. Taking the input number from the user.

3. Finding the digits in that given number.

4. Passing those variables to the program.

Printing the Last Digit of a Number

In this program first, we will take the input number from the user. Then we will separate the digits from that number. And at last, we will print the last digit of the number.

Let us take the example program from the below code for printing the Last Digit of a Number.

Program Code:-

#include <stdio.h>
int main()
{
    //Declaring the required variable for the program.
    int n, sum=0, ldigit;
    //n = it will hold the input integer value. 
    //fdigit = it will hold the first integer value. 
    //ldigit = it will hold the last integer value. 
    //sum = it will hold the integer value. 
    //takling the input number from the user.
    printf("Enter number = ");
    scanf("%d", &n);
    // Finding the last digit of a number
    ldigit = n % 10;
    //Finding the first digit by dividing n by 10 until n greater then 10
    while(n >= 10)
    {
        n = n / 10;
    }
    
    //printing the output digit first and the last digit
    printf("last digit = %d\n\n", ldigit);
    return 0;
}

#include <stdio.h>

int main()

{

//Declaring the required variable for the program.

int n, sum=0, ldigit;

//n = it will hold the input integer value.

//fdigit = it will hold the first integer value.

//ldigit = it will hold the last integer value.

//sum = it will hold the integer value.

//takling the input number from the user.

printf("Enter number = ");

scanf("%d", &n);

// Finding the last digit of a number

ldigit = n % 10;

//Finding the first digit by dividing n by 10 until n greater then 10

while(n >= 10)

{

n = n / 10;

}

//printing the output digit first and the last digit

printf("last digit = %d\n\n", ldigit);

return 0;

}

In the above program, we have first initialized the required variable.

n = it will hold the integer value.
ldigit = it will hold the integer value.
sum = it will hold the integer value.

What are the digits in the number?

The number of integers in a number is called its digits. A number is said to be a single-digit number when it is between 0 and 9. Hence, the number is said to be a 4-digit number when it is between the range of 1000 and 9999. in c programming, we can print the first and last digit from the number with the help of a small program.

Algorithm:-

1. Declaring the variables for the program.

2. Taking the input number from the user.

3. Finding the digits in that given number.

4. Passing those variables to the program.

5. Printing the First and Last Digit of a Number.

6. Printing the resultant digits to the user.

7. End the program.

Printing the First and Last Digit of a Number

In this program first, we will take the input number from the user. Then we will separate the digits from that number. And at last, we will print the first and the last digit of the number.

Let us take the example program from the below code for printing the First and Last Digit of a Number.

Program Code:-

#include <stdio.h>
int main()
{
    //Declaring the required variable for the program.
    int n, sum=0, fdigit, ldigit;
    //n = it will hold the input integer value. 
    //fdigit = it will hold the first integer value. 
    //ldigit = it will hold the last integer value. 
    //sum = it will hold the integer value. 
    //takling the input number from the user.
    printf("Enter number = ");
    scanf("%d", &n);
    // Finding the last digit of a number
    ldigit = n % 10;
    //Finding the first digit by dividing n by 10 until n greater then 10
    while(n >= 10)
    {
        n = n / 10;
    }
    fdigit = n;
    //printing the output digit first and the last digit
    printf("first digit = %d and last digit = %d\n\n", fdigit,ldigit);
    return 0;
}

#include <stdio.h>

int main()

{

//Declaring the required variable for the program.

int n, sum=0, fdigit, ldigit;

//n = it will hold the input integer value.

//fdigit = it will hold the first integer value.

//ldigit = it will hold the last integer value.

//sum = it will hold the integer value.

//takling the input number from the user.

printf("Enter number = ");

scanf("%d", &n);

// Finding the last digit of a number

ldigit = n % 10;

//Finding the first digit by dividing n by 10 until n greater then 10

while(n >= 10)

{

n = n / 10;

}

fdigit = n;

//printing the output digit first and the last digit

printf("first digit = %d and last digit = %d\n\n", fdigit,ldigit);

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

n = it will hold the integer value.
fdigit = it will hold the integer value.
ldigit = it will hold the integer value.
sum = it will hold the integer value.

In this program first, we will take the input number from the user. Then we will separate the digits from that number. Now we will add those first and last digits. And at last, we will print that output number

Let us take the example program from the below code for Add First and Last Digit of a Number.

Program Code:-

/**

 */

#include <stdio.h>

int main()
{
    //declaring the required variable for the program.
    int num, sum=0, fdigit, ldigit;

    /* Taking the Input a number from user */
    printf("Enter any number to find sum of first and last digit: ");
    scanf("%d", &num);
    
    /* Find last digit to sum */
    ldigit = num % 10;
    /* Copy num to first digit */
    fdigit = num;
    /* Find the first digit by dividing num by 10 until first digit is left */
    while(num >= 10)
    {
        num = num / 10;
    }
    fdigit = num;
    /* Find sum of first and last digit*/
    sum = fdigit + ldigit; 
    //printing the output number.
    printf("Sum of first and last digit = %d", sum);

    return 0;
}

/**

#include <stdio.h>

int main()

{

//declaring the required variable for the program.

int num, sum=0, fdigit, ldigit;

/* Taking the Input a number from user */

printf("Enter any number to find sum of first and last digit: ");

scanf("%d", &num);

/* Find last digit to sum */

ldigit = num % 10;

/* Copy num to first digit */

fdigit = num;

/* Find the first digit by dividing num by 10 until first digit is left */

while(num >= 10)

{

num = num / 10;

}

fdigit = num;

/* Find sum of first and last digit*/

sum = fdigit + ldigit;

//printing the output number.

printf("Sum of first and last digit = %d", sum);

return 0;

}

num = it will hold the integer value.
fdigit = it will hold the integer value.
ldigit = it will hold the integer value.
sum = it will hold the integer value.
