In most C-derived languages (C, Java, Javascript, etc), the for
loop is of the same basic syntax
for (int i = 0; i < 100; i++) {
// code here
}
Why does this syntax contain semicolons, when semicolons are usually reserved for the end of the line? Also, why is there no semicolon after i++
?
This pseudo-code:
for (A; B; C) {
D;
}
can be internally converted to
{ // scope bracket
A;
while (B) {
D;
C;
}
}
