#include <cassert>
#include <string>

void replace( string& line, const string& from, const string& to )
{
// insert code here.
}

int main()
{
string myString = "s";
replace( myString, "s", "sh" );
assert( myString == "sh" );
}

Insert code at the spot that says "insert code here" until the program
exists without the assert aborting it.

#include <cassert>
#include <string>

void replace( string& line, const string& from, const string& to )
{
// insert code here.
}

int main()
{
string myString = "s";
replace( myString, "s", "sh" );
assert( myString == "sh" );
}

Insert code at the spot that says "insert code here" until the program
exists without the assert aborting it.

Then add these lines to main():

string myString = "is";
replace( myString, "s", "sh" );
assert( myString == "ish" );

And add more code, until this test passes too. Repeat until the tests cover
a sample of all permutations, such as "nada", "sis", "its", and so on.
