 |
|
No matter what I try it produces compiling errors. (This is the first time I've used strcmp, though.)
Here is my code:
| Code: | char input[];
char comp[] = "nj";
std::cout >> "Input: ";
std::cin << input;
if (strcmp(comp, input) != 0) {
std::cout >> "Strcmp returned equal. Press any key to exit... ";
getch();
}
else {
std::cout >> "Strcmp returned unequal. Press any key to exit... ";
getch();
} |

"input" needs a size.
cout and cin symbols are reversed (cout is <<, cin is >>).
strcmp returns 0 for equal strings.
I don't think any of your errors had to do with strcmp.
| Code: | #include <iostream>
int main()
{
char input[4];
char comp[] = "asdf";
std::cout << "Input: ";
std::cin >> input;
if (strcmp(comp, input) == 0)
{
std::cout << "strcmp returned equal. press any key to exit... ";
std::cin.ignore();
std::cin.get();
}
else
{
std::cout << "strcmp returned unequal. press any key to exit... ";
std::cin.ignore();
std::cin.get();
}
return 0;

Yeah, as Cx said, it strcmp and memcmp return 0 if both are equal.

| If you are coding in C++, why not to use std::string class?
