C Program for Vote Eligibility:

Basic info: if a person's age is greater than 18, then he is eligible to vote.If age<18 then not eligible. 

Here  to check the age and decide whether a person is eligible or not, we simply need to compare if age≥18 .

First Let's Build The Logic:

if age ≥ 18 (age greater than or equal to 18): Eligible to vote

else: Not Eligible to Vote

Let's develop a C program for the above logic:

  • First, we need to take the age as input from the user:

int age;

printf("Enter your age: ");

scanf("%d", &age)

  • Then we need to compare the age using the if-else condition and print the output:

if (age >= 18)
       printf("You are eligible to vote.\n");
else
      printf("You are not eligible to vote.\n");

Source Code: 
#include <stdio.h>
int main() {
    int age;
    printf("Enter your age: ");
    scanf("%d", &age);
    if (age >= 18)
        printf("You are eligible to vote.\n");
    else
        printf("You are not eligible to vote.\n");
    return 0;
}
Input: 
CASE-1:
Enter your age: 17
CASE-2:
Enter your age: 29
Output: 
CASE-1:
You are not eligible to vote.
CASE-2:
You are eligible to Vote.
