C program to toggle case of a string using while loop.




#include <stdio.h>

#define MAX 100
void toggleCase(char * text);


int main()
{
    char text[MAX];

    printf("\n Enter any string: ");
    gets(text);

    printf("\n String before toggling case: %s", text);

    toggleCase(text);

    printf("\n String after toggling case: %s", text);

    return 0;
}

void toggleCase(char * text)
{
    int i = 0;

    while(text[i] != '\0')
    {
        if(text[i]>='a' && text[i]<='z')
        {
            text[i] = text[i] - 32;
        }
        else if(text[i]>='A' && text[i]<='Z')
        {
            text[i] = text[i] + 32;
        }

        i++;
    }
}


Output:

 Enter any string: I love c programming
String before toggling case: I love c programming
String after toggling case: i LOVE C PROGRAMMING
Process returned 0 (0x0) execution time : 11.406 s

Enter any string: Programming
String before toggling case: Programming
String after toggling case: pROGRAMMING
Process returned 0 (0x0) execution time : 9.981 s
