This problem helps you practice core C++ fundamentals in a practical way. It builds intuition around pass, student, mark. Let’s break it down step by step so you can implement it confidently.
Problem Statement
A student needs 40 marks to pass. Check if student passed or failed.
Input Format
An integer marks.
Output Format
Print
• Pass
OR
• Fail
Constraints
• Marks range: 0 to 100
Concept Explanation
A student passes only if marks are 40 or more.
Step-by-Step Logic
1.Take input marks.
2.If marks ≥ 40:
• Print Pass.
3.Else:
• Print Fail.
Code Solution
This explanation is written for learning purposes and to help beginners understand the concept clearly.
oid control_q1_pass_fail() {
int marks = 65;
int passingMarks = 40;
cout << "Student marks: " << marks << endl;
if(marks >= passingMarks) {
cout << "Result: PASS" << endl;
} else {
cout << "Result: FAIL" << endl;
}
}
Common Mistakes
- Misreading input/output format.
- Not handling constraints and edge cases.
- Off-by-one errors in loops.
- Forgetting to reset variables between test cases (if any).
