C++错误：向量下标超出范围，行1201

Question

新增至C++。尝试调试代码时，我收到“超出范围”的错误消息。我试图使用resize（），但它仍然没有修复。代码是将指令读入2d矢量并打印出图形。 我在做什么错？

    characters.token = '@'; 
    characters.isOuter = false; 
    characters.isTriangular = false; 

    Builder(characters, key); 
    Printer(key);

    if (character.token == 0) 
     c = 'a'; 
    else 
     c = character.token; 

    matrix.resize(character.rowNum); 
    for (int i = 0; i < character.rowNum; i++){ 
     if (character.isTriangular) 
      matrix[i].resize(i + 1); 
     else 
      matrix[i].resize(character.colNum); 

     if (character.isOuter)

if (i = j)应该是if (i == j)。

if (i = j)做一个任务和测试是否i != 0。

其他问题：

while (i <= j){ 
    for (i = 0; i < character.rowNum; i++) 
     for (j = 0; i < character.colNum; j++) // You test `i` instead of j 
      matrix[i][j] = c; 
    // Once test fixed 
    // Here `i == character.rowNum` and `j == character.colNum` (if `character.rowNum != 0`) 
    // So the while loop condition doesn't change and may so do infinite loop 
}
