Basic C Programming Practice - Practice 4

=> Write a program in C to check whether upper, lower, number or not?


Solution :

#include<stdio.h>

#include<conio.h>

main()

{

      char ch;

      printf("Please Enter Your Quarry : ");

      scanf("%c",&ch);

      if(ch>='A'&&ch<='Z')

      printf("It's An Upper Case Character.");

      else

      if(ch>='a'&&ch<='z')

      printf("It's An Lower Case Character.");

      else

      if(ch>='0'&&ch <='9')

      printf("It's Number");

      else

      Printf("Please Enter A Valid Character.");

      getch();

      }

Program Analysis :

Here ch is a character type variable and  we use %c to take character type input from terminal or keyboard.If we declare any single character than we must use single quot ( ' ' ).

Then we simply declare our condition through if else if Decision Control Statement and It's done !!!
