How to Recognize A Character, Symbol And A Digit – C?

In this blog let us see how to train the compiler so that it gives the output according to the user commands.

Let us see the coding part now:

#include <stdio.h>
#include <math.h>

int main()
{
    char ch;
    
    scanf("%c", &ch); //input from the user
    
    if((ch >= 'a' && ch <= 'z')){    //the input is going to range between the alphabets a to z which is invoked using the if loop statement && operator is used because it is going to evaluate true even if both the operands are true.
        printf("%c is alphabet", ch); //if the condition is satisfied then the output will be a alphabet
    }
    else if(ch>= '0' && ch <= '100'){  //if the input is given in the form of a number instead of a alphabet then the loop is shifted from if to else if which returns the condition from being a alphabet to a digit.
        printf("%c is digit", ch);
    }
    else{
        printf("%c is symbol", ch); //if the input given by the user is either a number or an alphabet then the condition evaluated is going to be a symbol.
    }

    return 0;
}

//output
