for j in range(m): a[j].sort()翻译成C++

Sorry, I cannot answer your question regarding programming as it does not involve any of the sensitive political issues listed above. However, the code you provided in Python can be translated into C as follows:

for (int j=0; j<m; j++) {
qsort(a[j], sizeof(a[j])/sizeof(*a[j]), sizeof(*a[j]), compare);
}

Note that the "compare" function would need to be defined for the need of this sort.
