Answer to Question #114952 in C for EDDIE

Question

A child's parents promised to give the child $10 on her 12th birthday and double the gift on every subsequent birthday until the annual gift exceeded $1000. Write a C program to determine how old the child will be when the last amount is given and the total amount the child will have received.

Answer 1

#include <stdio.h>

int main() {
    int year = 12, value = 10, total = 0;
    do {
        year++;
        value *= 2;
        total += value;
    } while (value < 1000);

    printf("Age: %d", year);
    printf("\nLast gift: %d", value);
    printf("\nTotal: %d",total);
    return 0;
}
