Question

Write a C program that asks the user to enter two real numbers. Then your program displays a menu that asks the user to choose what arithmetic operation to be done on those numbers. Depending on the user's entry, the program should display the result to the screen. The sample runs below show what should be done to the numbers entered by the user. Your program should run exactly like shown in the sample runs. make your code run as shown in the sample runs below.

Answer 1

Please find the code below::

#include <stdio.h>

#include <math.h>

void printOperations(){

printf("Enter \n");

printf(" 1\tto print the sum of the numbers\n");

printf(" 2\tto print the product/multiplication of the numbers\n");

printf(" 3\tto print the division of first number by second number\n");

printf(" 4\tto print the square root of the first number\n");

printf(" 5\tto Exit program\n");

printf("1,2,3 or 4 : ");

}

int main()

{

float n1,n2;

printf("Enter your first number : ");

scanf("%f",&n1);

printf("Enter your second number : ");

scanf("%f",&n2);

int choice;

float sum,mul,root,div;

while(1){

printOperations();

scanf("%d",&choice);

switch (choice) {

case 5 :

printf("Good bye!");

break;

case 1 :

sum = n1+n2;

printf("%.2f + %.2f = %.2f",n1,n2,sum);

break;

case 2 :

mul = n1*n2;

printf("%.2f * %.2f = %.2f",n1,n2,mul); break;

case 3 :

if(n2==0){

printf("Sorry you cannot divide by zero!\n");

continue;

}

div = n1/n2;

printf("%.2f / %.2f = %.2f",n1,n2,div);

break;

case 4 :

if(n1<0){

printf("Sorry we cannot square root a negative number!\n");

continue;

}

root = sqrt(n1);

printf("Square root of %.2f is %.2f",n1,root);

break;

default:

printf("Invalid option!!!");

break;

}

if(choice==5){

break;

}

printf("\n");

}

return 0;

}

output:
