Document Summary
Iteration statements: c provides three iteration statements: The while statement is used for loops whose controlling expression is tested before the loop body is executed. The do statement is used if the expression is tested after the loop body is executed. The for statement is convenient for loops that increment or decrement a counting variable. Loop structures while loop int number = 5; while (number>0) printf( %d, ,number); number--; Loop structures do-while loop int number; do { printf("enter a number (enter 0 to quit): ); scanf( %d ,&number); printf("you entered: %d\n ,number); For statement idioms: the for statement is usually the best choice for loops that. Count up (increment a variable) or count down (decrement a variable): a for statement that counts up or down a total of n times will usually have one of the following forms: Counting up from 0 to n 1: for (i = 0; i < n; i++) .
