C program that asks the user an arithmetic operator (‘+’, ‘-‘, ‘*’, or ‘/’ ) and two operands and perform the appropriate arithmetic operation on the operands

C program that asks the user an arithmetic operator (‘+’, ‘-‘, ‘*’, or ‘/’ ) and two operands and perform the appropriate arithmetic operation on the operands


Input:

Enter the input like + 25 45 to add 25 & 45:
+ 25 45

Output:

The sum of 25 & 45 is 70

Implementation:

#include <stdio.h> int main(void) { char ch; int n1,n2; printf("Enter the input like + 25 45 to add 25 & 45:\n"); scanf("%c %d %d",&ch,&n1,&n2); switch(ch) { case '+': printf("The sum of %d & %d is %d",n1,n2,(n1+n2)); break; case '-': printf("The difference of %d & %d is %d",n1,n2,(n1-n2)); break; case '*': printf("The product of %d & %d is %d",n1,n2,(n1*n2)); break; case '/': printf("The result of %d by %d is %f",n1,n2,(float)(n1/n2)); break; default: printf("Enter a valid symbol +, -, *, /"); break; } return 0; }
