C++ RGB(100,100,100,0.5) Validation
#include <iostream>
#include <cstdlib>
bool validateRGB(int r, int g, int b, float alpha) {
if (r >= 0 && r <= 255 && g >= 0 && g <= 255 && b >= 0 && b <= 255 && alpha >= 0.0 && alpha <= 1.0) {
return true;
} else {
return false;
}
}
int main() {
int red = 100;
int green = 100;
int blue = 100;
float alpha = 0.5;
if (validateRGB(red, green, blue, alpha)) {
std::cout << "RGB values and alpha are valid." << std::endl;
} else {
std::cout << "RGB values and alpha are not valid." << std::endl;
}
return 0;
}
Explanation:
1. Include necessary headers for input/output and standard library functions.
2. Define a function validateRGB
that takes in the RGB values (r, g, b) and alpha, and returns a boolean indicating whether the values are valid.
3. Inside the validateRGB
function, check if the RGB values are within the range [0, 255] and if the alpha value is within the range [0.0, 1.0].
4. In the main
function, initialize the red, green, blue, and alpha values.
5. Call the validateRGB
function with the RGB and alpha values as arguments.
6. Print a message indicating whether the RGB values and alpha are valid based on the return value of the validateRGB
function.
