Arithmetic Operators

#include <stdio.h>

int main() {
    int a = 10, b = 3;
    printf("a + b = %d\n", a + b);   // 13
    printf("a - b = %d\n", a - b);   // 7
    printf("a * b = %d\n", a * b);   // 30
    printf("a / b = %d\n", a / b);   // 3
    printf("a %% b = %d\n", a % b);  // 1 (remainder)

    int x = 5;
    x++;  // 6 (increment)
    x--;  // 5 (decrement)
    return 0;
}

Comparison Operators

Return 1 (true) or 0 (false):

int a = 10, b = 5;
printf("%d\n", a == b);   // 0 (equal to)
printf("%d\n", a != b);   // 1 (not equal)
printf("%d\n", a > b);    // 1 (greater than)
printf("%d\n", a < b);    // 0 (less than)
printf("%d\n", a >= 10);  // 1 (greater or equal)
printf("%d\n", b <= 5);   // 1 (less or equal)

Logical Operators

int x = 1, y = 0;
printf("%d\n", x && y);  // 0 (AND: both must be true)
printf("%d\n", x || y);  // 1 (OR: at least one true)
printf("%d\n", !x);      // 0 (NOT: reverses)

int age = 25, hasLicense = 1;
if (age >= 18 && hasLicense) {
    printf("You can drive!\n");
}

Assignment Operators

int c = 10;
c += 5;   // c = 15
c -= 3;   // c = 12
c *= 2;   // c = 24
c /= 4;   // c = 6
c %= 4;   // c = 2
