문자열 변환 함수를 사용하지 않고 대문자를 소문자로 변환하는 C 프로그램을 작성하세요.

#include <stdio.h>
#include <string.h>
int main(){
   char string[50];
   printf("enter a string to convert to lower case</p><p>");
   gets(string); /reading the string
   printf("The string in lower case: %s</p><p>", strlwr(string)); //strlwr converts all upper    to
   lower
   return 0;
}

enter a string to convert to lower case

The string in lower case: cprogramming language

#include<stdio.h>
void main(){
   //Declaring variable for For loop (to read each position of alphabet) and string//
   int i;
   char string[40];
   //Reading string//
   printf("Enter the string : ");
   gets(string);
   //For loop to read each alphabet//
   for(i=0;string[i]!=&#39;\0&#39;;i++){
      if(string[i]>=65&&string[i]<=90){
         string[i]=string[i]+32;
      }
   }
   printf("The converted lower case string is : ");
   puts(string);
}

Enter the string : TUTORIALSPOINT
The converted lower case string is : tutorialspoint
