by Dinesh Thakur Category: Basic Of C Programming

The function getchar () reads a single character at a time, i.e., it gives access to a single character which may be manipulated. For instance, the character may be changed by a new character, a lowercase letter may be changed to an upper case letter or vice versa, or a character may be removed from the string, and so on. However, for reading the complete string you have to use a loop.

#include<stdio.h>
#include<conio.h>
void main()
{
int a, b;
char ch;
printf("Choice:\n");
printf("Add, Subtract, Multiply, or Divide?\n");
printf("Enter first letter: ");
ch = getchar();
printf(“\n");
printf("Enter a: ");
scanf("%d", &a);
printf("Enter b: ");
scanf("%d", &b);
if(ch=='A')
printf("%d", a+b);
if(ch=='S')
printf("%d", a-b);
if(ch=='M')
printf("%d", a*b);
if(ch=='D' && b!=0)
printf("%d", a/b);
getch();
}
 
OUTPUT:
 
Choice
Add, Subtract, Multiply, or Divide?
Enter first letter: A
Enter a: 412
Enter b: 214
