The for keyword sets all three required looping conditions in its parentheses: initialization, the expression that remains true while the loop repeats, and an expression to execute each time the loop repeats. While complex, use a for loop as a way to construct a loop in one spot without worrying about overhead handled elsewhere in the code.
- [Instructor] Along with decision making, another way … to control program flow is one of the basic concepts … of computer programming, the loop. … A loop is one or more statements that repeat. … The loop's condition determines … how many times the statements repeat. … Three C language keywords deal with loops, … for, while and do. … Loops feature three parts, … a starting condition or initialization, … an expression that must remain true … for the statements to repeat … and an exit condition to terminate the loop. … In a for loop, all three conditions are expressed … in the keywords parentheses as shown in this exercise file. … The starting condition … or a loop initialization appears first. … Variable a is initialized to zero. … A semi-colon separates the expressions in a for statement. … Next comes the condition. … The loop repeats as long as the value … of variable a is less than 10, … then comes another semi-colon, … and then finally the expression … that's executed each time the loop repeats, …
