Ashima wants to print a pattern which includes checking and changing a variables value iteratively She decides to use a loop/condition Which of the following options should she use such that the body of the loop/condition is executed at least once whether the variable satisfies the entering condition or not ?
A. For loop
B. While loop
C. Do-while loop
D. Switch case
E. None of these
Answer : C. Do-while loop
Explanation:
Do While Loop :
- Unlike for and while loops, which test the loop condition at the top of the loop, the do…while loop in C programming checks its condition at the bottom of the loop.
- A do…while loop is similar to a while loop, except the fact that it is guaranteed to execute at least one time.
Syntax for Do While Loop :
do {
statement(s);
} while( condition );
