What is do while loop in C program?

There is given the simple program of c language do while loop where we are printing the table of 1.

• #include
• int main(){
• int i=1;
• do{
• printf(“\%d \n”,i);
• i++;
• }while(i<=10);
• return 0;

What is an example of a do loop?

The do while loop is an exit controlled loop, where even if the test condition is false, the loop body will be executed at least once. An example of such a scenario would be when you want to exit your program depending on the user input.

How do you convert Do While loop to for loop in C?

To convert a for loop to while loop we need to simply add the initialization statement before the while loop.

1. /* For loop */ int i; for(i = 0; i < 10; i++) { }
2. /* While loop */ while(*str++ != NULL) { length++;
3. /* Do while loop */ do. { status = check_connection();
4. /* For loop */ int i; for(i = 0; i < 10; i++) {

What is DO statement in C?

The C do while statement creates a structured loop that executes as long as a specified condition is true at the end of each pass through the loop. The syntax for a do while statement is: If the value of the expression is “false” (i.e., compares equal to zero) the loop is exited.

How do you use a loop?

A “For” Loop is used to repeat a specific block of code a known number of times. For example, if we want to check the grade of every student in the class, we loop from 1 to that number. When the number of times is not known before hand, we use a “While” loop.

What Continue does in C?

The continue statement passes control to the next iteration of the nearest enclosing do , for , or while statement in which it appears, bypassing any remaining statements in the do , for , or while statement body.

Do While loop in Java example with output?

DoWhileExample.java

• public class DoWhileExample {
• public static void main(String[] args) {
• int i=1;
• do{
• System.out.println(i);
• i++;
• }while(i<=10);
• }

What is do loop in computer?

(computing) A section of computer code in which an instruction or group of instructions is executed repeatedly depending on the value of a Boolean condition; either of a for loop or a while loop. …

What is the difference between while and do while loop in C?

1. While the loop is an entry control loop because firstly, the condition is checked, then the loop’s body is executed. The do-while loop is an exit control loop because in this, first of all, the body of the loop is executed then the condition is checked true or false.

What is while and do-while statement in C?

The expression in a do-while statement is evaluated after the body of the loop is executed. Therefore, the body of the loop is always executed at least once. Next, expression is evaluated. If expression is false, the do-while statement terminates and control passes to the next statement in the program.

What is the purpose of do-while statement?

The do… while statement creates a loop that executes a specified statement until the test condition evaluates to false. The condition is evaluated after executing the statement, resulting in the specified statement executing at least once.

What is looping in C programming language?

C programming Looping (while, do while, for) programs Looping is the process by which you can give instruction to the compiler to execute a code segment repeatedly, here you will find programs related to c looping – programs using for, while and do while. Here you will get nested looping (loop within loop) programs.

How to print a string in C program?

C program to print a string using various functions such as printf, puts. Consider the following code: printf(“Hi there! How are you doing?”); Hi there! How are you doing? The printf function prints the argument passed to it (a string). Next, we will see how to print it if it’s stored in a character array.

How do you print a string in a while loop?

Print a string using a loop: We can print a string using a while loop by printing individual characters of the string. #include . int main() {. char s[100]; int c = 0; gets(s); while (s[c] != ‘0’) {.

How to use printf() function in C/C++?

The function prints the string inside quotations. To use printf () in our program, we need to include stdio.h header file using the #include statement. The return 0; statement inside the main () function is the “Exit status” of the program. It’s optional. We use \%d format specifier to print int types.
