Arithmetic operators in c

 Arithmetic operators are used to perform arithmetic operations like addition, subtraction, multiplication, division and modulo.

Operator	Operation
+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Modulo

Example C program using arithmetic operators:

 
  #include <stdio.h>
  int main() {
        int ch, input1, input2, res;
        do {
                printf("Menu:\n");
                printf("1. Addition\n2. Subtraction\n");
                printf("3. Multiplication\n3. Division\n");
                printf("4. Modulo\n");
                printf("Enter your choice:");
                scanf("%d", &ch);
                printf("Enter your input1 and input2\n");
                scanf("%d%d", &input1, &input2);
                switch (ch) {
                        case 1:
                                res = input1 + input2;
                                break;
                        case 2:
                                res = input1 - input2;
                                break;
                        case 3:
                                res = input1 * input2;
                                break;
                        case 4:
                                res = input1 / input2;
                                break;
                        case 5:
                                res = input1 % input2;
                                break;
                        default:
                                printf("You have entered wrong option\n");
                                break;
                }
                printf("Result: %d\n", res);
                printf("Do you want to continue(0/1):");
                scanf("%d", &ch);
        } while (ch == 1);
        return 0;
  }
