How can I run C program again and again?

You can easily repeat your program by puting your code in a do-while loop. Now since you are using this for a calculator like program, You can ask the user to change value of x from 1 to something else within the program to exit at run time. Otherwise it will continue to run!

What is if and if else statement?

if statement – executes some code if one condition is true. if…else statement – executes some code if a condition is true and another code if that condition is false. … elseif…else statement – executes different codes for more than two conditions. switch statement – selects one of many blocks of code to be executed.

Which loop is faster in C language?

As for infinite loops for(;;) loop is better than while(1) since while evaluates every time the condition but again it depends on the compiler. Depends on the language and most likely its compiler, but they should be equivalent in most languages. It shouldn’t matter which is faster.

Which loop is better in C?

If you need only loop condition (tested at the beginning of the loop) then while is more elegant. Between for/while and do-while: in do-while the condition is evaluated at the end of the loop. More confortable if the loop must be executed at least once.

Which loop is guaranteed to execute at least one time?

do-while loopThe do-while loop is similar to the while loop, except that the test condition occurs at the end of the loop. Having the test condition at the end, guarantees that the body of the loop always executes at least one time.
