Iteration Statements

Iteration statements let you loop a set of statements. There are three forms of itera-
tion statements in C:

While Statement

Use the
statement is:
while ( expression ) statement
The
takes place before
on the first pass, the loop does not execute.
Parentheses around
Here is an example of calculating scalar product of two vectors, using the
statement:
int s = 0, i = 0;
while (i < n) {
s += a[i] * b[i];
i++;
}
Note that body of a loop can be a null statement. For example:
while (*q++ = *p++);
