C Operators

Introduction

An operator is a symbol that tells the compiler to perform a mathematical or logical operation. C has a rich set of operators used in expressions, conditions and assignments.

Operators are grouped by the number of operands they take and the type of operation they perform. Each topic below links to a dedicated tutorial with syntax, example programs and sample output.

Quick Example

#include <stdio.h>

int main(void) {
    int a = 10, b = 3;
    printf("Sum: %d\n", a + b);       /* arithmetic */
    printf("Equal? %d\n", a == b);    /* relational */
    printf("Both true? %d\n", a > 0 && b > 0);  /* logical */
    return 0;
}

Sample Output

Sum: 13
Equal? 0
Both true? 1
