Data types in 2_c languages (10) while, for

1 Loop Statement 1.1 while

while (condition), if the condition is true, the loop continues, the condition is false, and the loop ends

while (1), the notation of the dead loop

1.2 Continue

The loop encounters the continue statement, no longer executes the continue code below, but instead returns to the loop start statement and resumes execution of the loop

1.3 Break

Loop encounters break statement, immediate terminal loop, Loop end

1.4 Do While

Do

Compound statement

while (condition);

For do, the compound statement of the loop can be executed at least once

For while, it is possible that the compound statement will not have a single execution opportunity

1.5 for

for (int I = 0;i<10;i++)

1.6 Loop nesting

int i,j; for (i = 9; i > 0; i--) { for (j = 9; j > 0; j--) { printf ("%d\t", I * j); } printf ("\ n"); }
