WAP in C to take two numbers from the user without using scanf and print their sum

 Code:-

 here we use getch() for taking input of numbers.  As we know getch() take a character from the user .

But we can add only numbers which are less than 10. because getch() hold the screen untill we press a key so it can take only a character from the user.

#include<stdio.h>

int main()

{

char ch;

int a,b;

clrscr();

printf("Enter first number \n");

// taking first character

ch=getch();

a=ch;

a=a-48; // 48 is the ascii of 0

printf("Enter second number\n");

// taking second character

ch=getch();

b=ch;

b=b-48; // 48 is ascii of 0

printf("Sum of %d and %d is %d",a,b,a+b);

getch();

return 0;

}

Output:-

Enter first number

Enter second number

sum of 2 and 4 is 6
