Question

how to write a C-program that reads a capital letter character and converts it to small letter character?

Answer 1

if the ascii value of a character is less than that of 'Z' then it a capital number. add (int)'a'-(int)'A' to your characters of the string with the above condition

Answer 2

#include<stdio.h>

int main( )

{

     char a[10];

     printf("Enter the Capital Letters:");

     scanf("%s",a);

     int i;

     for(i=0;a[i]!='\0';i++)

     {

          if(a[i]>='A' && a[i]<='Z')

          {

             a[i] = a[i] + 32;

          }

    }

printf("converted Small Letters:%s",a);

}

Answer 3

#include <stdio.h>
#include <ctype.h>

void main()
{
    
    char input[10] = "helloHeLlO";
    int counter = 0;
    
    printf("String currently is: ");
    
    for(counter = 0; counter < 10; counter++){   
        printf("%c", input[counter]);
    }
    
    for(counter = 0; counter < 10; counter++){
    
        if(islower(input[counter])){
              continue;
        }
        else{
            input[counter] = tolower(input[counter]);
        }
    }
    
    printf("\nString converted to all lowercase is: ");
    for(counter = 0; counter < 10; counter++){   
        printf("%c", input[counter]);
    }
    
}

Answer 4
