4. Operators in C

Arithmetic, relational, logical, bitwise, assignment, and sizeof operators in C.

Arithmetic, relational, logical, bitwise, assignment, and sizeof.

Examples

Minimum of Two (min_of_two.c)

Demonstrates the ternary conditional operator (?:):

#include <stdio.h>

int main(void) {
    int a, b;
    printf("Enter two integers (a b): ");
    scanf("%d %d", &a, &b);
    int min = (a < b) ? a : b;
    printf("Min = %d\n", min);
    return 0;
}

Prime Check (is_prime.c)

Uses arithmetic (%), relational (<=, ==), and logical operators in a loop:

#include <stdio.h>

int is_prime(int n) {
    if (n <= 1) return 0;
    for (int i = 2; i * i <= n; i++) if (n % i == 0) return 0;
    return 1;
}

int main(void) {
    int n; printf("Enter n: "); scanf("%d", &n);
    printf(is_prime(n) ? "Prime\n" : "Not prime\n");
    return 0;
}
