String program help

[sanman10535]

I have to write a function char *string_replace (char *s, char c, char r) that replaces every instance of character c in string s with character r, and returns the resulting string.

I have created the following main function to test my program. I can change the values sent to the function string_replace to test your program. I will be using my own strings to test the program; so my program should be able to work with any input string.

Can someone help me with the coding for this program? This is what I have so far as for the test program.

# include <stdio.h>

main () {
	
	char *str = “The Gators Are Going To Beat Florida State Every Year”;

	char *result = string_replace (str, ‘a’, ‘c’);

	printf (“%s”, result);

	result = string_replace (result, ‘c’, ‘a’);

	printf (“%s”, result);
}

The output should be:

The Gctors Are going to bect Floridc Stcte every yecr.
The Gators Are going to beat Florida State every year.

A clue for you

int i = 0;
for ( i = 0 ; s[i] != '\0' ; i++ )

That steps through the string one character at a time

> char *str = “The Gators Are Going To Beat Florida State Every Year”;
Even in your test program, you will want
char str[] = “The Gators Are Going To Beat Florida State Every Year”;
This is an initialised array (which can be modified)
You had a string constant, which is likely not modifyable.

Look for sscanf(), scanf()
