of his joining date. Assume he’s

joining on 3rd of the month, then his starting

pay is Rs 9/. After that his pay for the consecutive days are twice the pay of

previous day .i.e. each day’s pay is twice the pay of previous day. Write a c

program using functions to find his total pay for 3

0 days.

Answer 1

#include <stdio.h>

int main()
{
    int day;
    double total;
    total = 0;        
    printf("Enter day of the month: ");
    scanf("%d", &day);
    total = total + (day * day);    // first day
    for (int i=0; i<29; i++)        // 2 .. 30 days
    {
        total = total * 2;
    }
    printf("\n\nTotal pay for 30 days (Rs): %.0f", total);
    getchar();  
}
