Youth Software Programming (C/C++) Level Exam

Preparing for CIE C++ Level 1! A 10-week plan of real exam questions to help your child confidently pass the first level!

Hello parents and students! As a teacher deeply involved in C++ programming education, I often receive many questions about “how to prepare efficiently” during the exam preparation season. For children about to take the C++ Level 1 exam, finding a scientific review path can often make preparation much more effective.

Today marks the final issue of our “10-week CIE C++ Level 1 Real Exam Plan”! Have you all diligently followed Teacher Zhu to complete these 10 sets of real questions? From the “beginner test” in the first week to now’s “pre-exam sprint“, each review of the questions and consolidation of each exam point is the “exam confidence” you have quietly built up~

The exam is just around the corner, remember: take your time with the questions, code steadily, and just “bring out” the knowledge points you have practiced well! I believe that your efforts over these 10 weeks will surely shine in the exam~

01

Character Rectangle

• Core Exam Point: Character Output and Loop Control

• Specific Exam Points:

1. Processing of single character input;

2. Application of double loops;

3. Continuous output operation of characters;

1. Appropriate output of newline characters.

#include <iostream>using namespace std;
int main(){    char ch;    cin >> ch;    for (int i = 1; i <= 3; i++) // Outer loop for rows    {        for (int j = 1; j <= 4; j++) // Inner loop for columns        {            cout << ch;        }        cout << endl;    }    return 0;}

02

Rectangle Area

• Core Exam Point: Basic Arithmetic Operations

• Specific Exam Points:

1. Processing of multiple variables in a single line;

2. Implementation of basic multiplication operations;

3. Variable definition and data type selection;

4. Simple input → calculation → output flow;

5. Value range validation (length and width not exceeding 1000).

#include <iostream>using namespace std;
int main(){    int a, b;    cin >> a >> b;    cout << a * b;     return 0;}

03

Grade Level Conversion

• Core Exam Point: Multi-conditional Branch Judgement

• Specific Exam Points:

1. Processing of single integer input;

2. Multi-branch structure;

3. Correct handling of boundary values (including endpoint values).

#include <iostream>using namespace std;
int main(){    int s;    cin >> s;    if (90 <= s && s <= 100) cout << "A";
    else if (77 <= s && s <= 89) cout << "B";
    else if (67 <= s && s <= 76) cout << "C";
    else if (60 <= s && s <= 66) cout << "D";
    else cout << "E";
    return 0;}

• Core Exam Point: Array Processing and Historical Data Comparison

• Specific Exam Points:

1. Array input processing (first input n, then input n scores);

2. Array traversal and element access;

3. Comparison of historical data with current data;

4. Application of Boolean logic (existence judgment);

5. Nested use of multiple loops;

6. Real-time output combined with conditional judgment.

#include <iostream>using namespace std;int a[110];
int main(){    int n;    cin >> n;    for (int i = 1; i <= n; i++)    {        cin >> a[i];    }    for (int i = 1; i <= n; i++) // Enumerate each score a[i]     {        bool flag = false;        for (int j = 1; j < i; j++) // Enumerate each score before a[i]        {            if (a[j] < a[i]) flag = true;        }        if (flag == false) cout << "N" << endl;        else cout << "Y" << endl;    }    return 0;}

05

Finding Special Year Numbers

• Core Exam Point: Number Processing and Loop Searching

• Specific Exam Points:

1. Digit separation technique;

2. Looping incrementally to find numbers that meet conditions;

3. Implementation of digit sum;

4. Combination of condition judgment and loop control;

5. Efficiency considerations for search algorithms;

1. Boundary handling (year numbers may exceed 9000).

#include <iostream>using namespace std;
int main(){    int y;    cin >> y;    for (int i = y + 1; ; i++)     {        int q = i / 1000 % 10;        int b = i / 100 % 10;        int s = i / 10 % 10;        int g = i % 10;                        if (q + b + s + g == 20)        {            cout << i;            break;        }    }    return 0;}
