Write a program to convert a string (of up to 20 characters, including the terminating null character) to all uppercase characters. After getting a string that could include spaces (use the fgets () function and don't forget to strip off the ending if it is there), display the original string. Pass the string to a void function (since the 'string' is really as character array) and have the function convert the string to all uppercase by iterating through the string using a for loop and the strlen () function (which is part of the string. h library), and using the toupper () function (which is part of the ctype. h library) to convert each character in the string. Then, back in the main program, display the all uppercase string.

Explanation:

#include

void MyToUpper (char * p)

{

int i;

for (i=0; i
{

p[i]=toupper (p[i]);

}

}

int main (void) {

char str[20];

printf ("Enter a string:");

fgets (str, 20, stdin);

printf ("The string you entered was: %s/n", str);

MyToUpper (str);

printf ("The string converted to uppercase is: %s/n", str);

fflush (stdin);

return 0;
