== 实际应用案例 ==  
=== 案例1：打印乘法表 ===  
<syntaxhighlight lang="cpp">  
for (int i = 1; i <= 9; i++) {  
    for (int j = 1; j <= i; j++) {  
        cout << j << "×" << i << "=" << i * j << "\t";  
    }  
    cout << endl;  
}  
</syntaxhighlight>  
'''输出：'''  
<pre>  
1×1=1  
1×2=2    2×2=4  
1×3=3    2×3=6    3×3=9  
...  
</pre>  

=== 案例2：二维数组遍历 ===  
<syntaxhighlight lang="cpp">  
int matrix[2][3] = {{1, 2, 3}, {4, 5, 6}};  
for (int row = 0; row < 2; row++) {  
    for (int col = 0; col < 3; col++) {  
        cout << matrix[row][col] << " ";  
    }  
    cout << endl;  
}  
</syntaxhighlight>  
'''输出：'''  
<pre>  
1 2 3  
4 5 6  
</pre>
