Answer 1

Arun Yadav you are using C code in C++ playground. So if you want to execute first remove old obsolete function getch() and conio.h library, clrscr(); which is only turbo c standard

#include <stdio.h>

int main()
{
int a,b;

printf("Enter the first number:");
scanf("%d",&a);
printf("Enter the second number:");
scanf("%d",&b);
int c=a+b;
printf("Sum of the two numbers is: %d",c);
return 0;
}

in C++ codeplayground something like that would work if u used functionality with cin
