Iteration expression is outside of for loop CXX-W1240
Anti-pattern
Minor
The following is the syntax of a for loop.
attr (optional) for ( declaration-or-expression (optional) ; condition (optional) ; iteration-expression (optional) ) statement
Though the last part of the loop i.e. "iteration-expression" is optional, missing it out or moving it to the body of the for loop defeats the purpose of using a for loop.
If such is the requirement, consider using a while.
Bad practice
int main(int argc, char** argv) {
for (int i = 0; i < argc - 1; /* missing iter-expr */) {
printf("arg %d of %d", i, argc);
i++; // bad
}
}
Recommended
int main(int argc, char** argv) {
for (int i = 0; i < argc - 1; i++) {
printf("arg %d of %d", i, argc);
}
}
int main(int argc, char** argv) {
int i = 0;
while (i < argc - 1) {
printf("arg %d of %d", i, argc);
i++;
}
}
