零长度数组 structline{intlength;charcontents[0]; };structline*thisline = (structline *)malloc(sizeof(structline) + this_length); thisline->length = this_length; 借用官方的示例说明以下,申请了一块空间,多出来的就是contents的内容。优点 contents不占用空间,struct line的大小就是int length的大小。...

However, for every argument of character type, the Fortran routine passes an additional argument giving the length of the string. These are long int quantities in C, passed by value.The order of arguments is:Address for each argument (datum or function) ...
我们可以看到Purify的报告中有两个内存错误,一个是ABR(Array Bounds Read)——数组越界读,一个是12个字节的Memory Leaked,展开小三角符号,我们可以看到更为详细报告: 展开ABR错误后,我们可以看到,ABR错误的产生是由printf产生的,而产生错误的内存是mystr。通过观察,我们马上可以发现为会什么会出现ABR错误,原因是C/...
