Introduction

C program to detrermine a candidate’s age is eligible for casting the vote or not. I have used DEV-C++ compiler for debugging purpose. But you can use any C programming language compiler as per your availability.

#include <stdio.h>

int main()
{
    int Candiateage;

    printf("Input the age of the candidate : ");
    scanf("%d", &Candiateage);

    if (Candiateage < 18)
    {
        printf("Sorry, You are not eligible to caste your vote.\n");
        printf("You would be able to caste your vote after %d year.\n", 18-Candiateag);
    }

    else
    {
        printf("Congratulation! You are eligible for casting your vote.\n");
    }
    return 0;

}
