Operator Meaning of Operator + addition or unary plus - subtraction or unary minus * multiplication / division % remainder after division( modulo division) // C Program to demonstrate the working of arithmetic operators #include <stdio.h> int main() { int x = 9,y = 4, c; c = x+y; printf("x+y = %d \n",c); c = x-y; printf("x-y = %d \n",c); c = x*y; printf("x*y = %d \n",c); c=x/y; printf("x/y = %d \n",c); c=x%y; printf("Remainder when x divided by y = %d \n",c); return 0; }
