While Loop Examples: Example 1: /* echo.c -- repeats input */#include <stdio.h>intmain(void){intch;/* * 1. getchar() function reads-in one character from the keyboard * at a time * 2. return type of getchar() is int * 3. getchar() returns integer value corresponding to cha...
Let us understanddo while loop in Cwith help of an example. syntax: do { /*block of statement*/ }while(condition); Explanation of do while loop in C: Here, while and do are the keywords in C language which is know to the compiler. Condition can be any expression. This is very sim...
Now, just as we saw in the for loop, there can be various ways in which we can achieve this result. C while Loop: Example 2 Print integers from 1 to 5 using the while loop. #include<stdio.h>intmain(){inti;//loop counter//method 1printf("Method 1...\n");i=1;while(i<=5)...
// infinite do...while loopintcount =1;do{// body of loop}while(count ==1); In the above programs, theconditionis alwaystrue. Hence, the loop body will run for infinite times. for vs while loops Aforloop is usually used when the number of iterations is known. For example, ...
This example is functionally equivalent to the first while loop example above and will result in an infinite loop. While vs Do While Let's consider the previous while loop boolean trigger example. If I had initialized the value of keepGoing as false, the code in the while loop would have ...
In the code above, we are not changing the value oni, hence the condition in thewhileloop will never fail. #include <stdio.h> int main() { do{ printf("Infinite loop\n"); } while(1); return 0; } Another example, with a constant value as condition, which is alwaystruehence the ...
The do...while loop is used to run a block of code multiple time until a specific condition is true. In this tutorial, we will learn about the do-while loop its use, syntax, example.
Example int i = 0;do { cout << i << "\n"; i++;}while (i < 5); Try it Yourself » Do not forget to increase the variable used in the condition, otherwise the loop will never end!Exercise? What is a key difference between a do/while loop and a while loop? A do/while...
} while ( x != 0 ); cin.get(); }Keep in mind that you must include a trailing semi-colon after the while in the above example. A common error is to forget that a do..while loop must be terminated with a semicolon (the other loops should not be terminated with a semicolon, ad...
while($i < 9); ?> The above code outputs: 9 Notethe above example outputs 9 only. This is because the do… while loop is executed at least once even if the set condition evaluates to false. Summary The for… loop is used to execute a block of a specified number of times ...
