Copy String Without Using strcpy

As we all know the String is a collection of character data types. In strings, only one variable is declared which can store multiple values. First will take the string from the user. Then will pass that string to a for loop for copying. The C programming language has many pre-defined functions for string manipulation. but in today’s tutorial, we will do without using strcpy().

With the help of this program, we can Copy String Without Using strcpy

Algorithm:-

1. Declaring the variables for the program.

2. Add a sting to the variable

3. Print the given string.

4. Now pass thatstring to for loop for copying

5. Printing the result string.

6. End

Program to Copy String Without Using strcpy:-

#include <stdio.h>
int main() 
{
    //declaring variables
    char string1[100], string2[100], i;
    //taking input string from the user
    printf("Enter string 1 to be copied: ");
    //putting string in 1 variable
    fgets(string1, sizeof(string1), stdin);
    //Adding that string to another variable
    for (i = 0; string1[i] != '\0'; ++i) 
    {
        string2[i] = string1[i];
    }
    
    string2[i] = '\0';
    //printing output of string copied without strcpy
    printf ("Copied string 2 without strcpy(): %s", string2);
    return 0;
}

#include <stdio.h>

int main()

{

//declaring variables

char string1[100], string2[100], i;

//taking input string from the user

printf("Enter string 1 to be copied: ");

//putting string in 1 variable

fgets(string1, sizeof(string1), stdin);

//Adding that string to another variable

for (i = 0; string1[i] != '\0'; ++i)

{

string2[i] = string1[i];

}

string2[i] = '\0';

//printing output of string copied without strcpy

printf ("Copied string 2 without strcpy(): %s", string2);

return 0;

}

Output:-

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

string1[100] = it will hold the string value.
string2[100] = it will hold the string value.

i = it will hold the integer value for the loop.

Taking Input string from the user.

Reading the input string from the user.

Copying the string with the help of for loop without using strcpy() function.

Printing output copied string2 without strcpy.
