Handling Conditional Logic Errors

As an experienced C++ coder, I've faced a perplexing problem with conditional expressions in my code. While implementing conditional logic to regulate program flow, I found unexpected behavior that contradicted the desired logic. Despite precisely designing the circumstances, the software fails to execute the necessary statements or generates incorrect results.
`#include <iostream>
int main() {
int score = 85;
// Categorize students based on exam scores
if (score >= 90) {
std::cout << "Excellent performance!";
} else if (score >= 70) {
std::cout << "Good performance.";
} else {
std::cout << "Needs improvement.";
}
return 0;
}
`
The situation plays out as follows: In a C++ software meant to categorize students based on exam scores, I used if-else statements to identify their performance levels, as described here. However, after running the application, I find inconsistencies in the categorizing process, resulting in erroneous classifications and potentially misleading results.
To properly handle this difficulty, I'm looking for advice on detecting and correcting mistakes in conditional statements, as well as ensuring that the program evaluates conditions correctly and executes related statements as intended. Furthermore, understanding best practices for designing and optimizing conditional logic in C++ will considerably improve my programming and debugging skills.

The code you provided appears to be correct in terms of the logic you've described. It categorizes students based on their exam scores into "Excellent performance," "Good performance," or "Needs improvement." However, if you're experiencing unexpected behavior, there may be other factors at play, such as the value of
scorenot being what you expect.To debug this, you can add some additional output to your program to see what value
scoreis taking on:#include <iostream>
int main() {
int score = 85;
// Print the value of score
std::cout << "Score: " << score << std::endl;
// Categorize students based on exam scores
if (score >= 90) {
std::cout << "Excellent performance!";
} else if (score >= 70) {
std::cout << "Good performance.";
} else {
std::cout << "Needs improvement.";
}
return 0;
}
