C Program to Convert String from UPPERCASE to lowercase

Here we will discuss about the conversion of UPPERCASE to Lowercase of any string value.
if(the string[i]<=65 and string[i]>97) then we add 32 in the string[i]+32.
For Example:
string-> "CPROGRAMMINGSIMPLY"
The Conversion in lowercase is "cprogrammingsimply".

ALGORITHM:-

step 1 : Start
step 2 : Take an character array
step 3 : Input from user in array
step 4 : Check is string [i] element greater then equal 65 and less then equal 90
step 5 : Set the string [i] = string[i]+32;
step 6 : Repeat the 4,5 step
step 7 : Stop the Execution

PROGRAM CODE:-

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

void main()
{
    char str[20];
    int i;
    clrscr();
    printf("Enter any string->");
    scanf("%s",str);
    for(i=0;i<=strlen(str);i++)
    {
        if(str[i]>=65&&str[i]<=90)
        {
            str[i]=str[i]+32;
        }
    }
    printf("\nThe string in lower case is->%s",str);
    getch();
}

OUTPUT:-

Enter an string : CPROGRAMMINGSIMPLY
 
The string in lower case is: cprogrammingsimply
