/* Taking the Input amount number from user */

printf("\n Please Enter the Amount of Cash = ");

scanf("%d", &Amount);

//calculating the notes for the amount.

flag = Amount;

for(i = 0; i < 8; i++)

{

//Printing the amount in the form of notes.

printf("\n %d Notes is = %d", a[i], flag / a[i]);

flag = flag % a[i];

}

Output:-

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

Amount = it will hold the integer value for the input.
i = it will hold the integer value for the controlling of the loop.
flag = it will hold the temporary integer value.

Taking the input amount from the user.

    //declaring the required variables for the program.
    int days, years, weeks;
    //days = it will the number of days taken in input from the user.
    //years = it will the number of years converted.
    //months = it will the number of weeks converted.
    
    /* Taking the Input total number of days from user */
    printf("Enter days: ");
    scanf("%d", &days);
     

    // Converts days to years, weeks and days
    years = days/365; 
    weeks = (days % 365)/7;
    days = days- ((years*365) + (weeks*7));

    //Printing the number of years after conversion.
    printf("Years: %d\n", years);
    //Printing the number of weeks after conversion.
    printf("Weeks: %d\n", weeks);
 

    return 0;
}

/* C Program to Convert Days to Years Weeks and Days */

#include <stdio.h>

int main()

{

//declaring the required variables for the program.

int days, years, weeks;

//days = it will the number of days taken in input from the user.

//years = it will the number of years converted.

//months = it will the number of weeks converted.

/* Taking the Input total number of days from user */

printf("Enter days: ");

scanf("%d", &days);

// Converts days to years, weeks and days

years = days/365;

weeks = (days % 365)/7;

days = days- ((years*365) + (weeks*7));

//Printing the number of years after conversion.

printf("Years: %d\n", years);

//Printing the number of weeks after conversion.

printf("Weeks: %d\n", weeks);

return 0;

}

Output:-

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

days = it will hold the integer value for the input.
years = it will hold the integer value.
weeks = it will hold the integer value.

Taking the input day from the user.

Converting the days to years.

Printing output.
