When i becomes 11, i < 11 will be false, and the for loop terminates. Example 2: for loop // Program to calculate the sum of first n natural numbers // Positive integers 1,2,3...n are known as natural numbers #
Case2 (Always FALSE condition): Variables ‘i’ is initialized before ‘do-while’ loop to ‘20’; iteration is increment of counter variable ‘i’; condition is FALSE always as ‘0’ is provided that causes NOT to execute loop statements, but it is noted here in output that loop stateme...
Syntax and Examples of For Loop in C Programming The essential syntax of a for loop in C is: for ( ; ; ) This for loop lacks an evaluation expression. If nothing is evaluated as true or false, there can be no exit to this loop. If this program ran, it would begin an infinite ...
Real-Life ExamplesTo demonstrate a practical example of the for loop, let's create a program that counts to 100 by tens:Example for (i = 0; i <= 100; i += 10) { printf("%d\n", i);} Try it Yourself » In this example, we create a program that only print even numbers ...
Loops are very useful when you want to perform a task repeatedly. Loop's body has set of statements, which gets executed on every iteration until a given condition is met. We have three types of loops in C. The working of these loops are almost similar,
After skipping the loop, the program executes the statements following the label. In this case, it prints the message “Skipped number 5.” to indicate that the number 5 was skipped. Conclusion In this blog, we have discussed the three main loops in C: for, while, and do-while. Each ...
The for loop The while loop, and The do...while loopThese loops are explained in detail as under.1. The for loopThe for loop is the most commonly used loop by the programmers and requires us to initialize three conditions in a single line at the start of the loop....
For loop Examples Example - 1: The following program calculate the sum of 1+2+3+...+50. The sum is stated in sum = sum + x, where i takes values from 1 to 50. #include<stdio.h>main(){intsum;intx;sum=0;for(x=1;x<=50;++x)// x take values in {1,2,3,...,50}{sum...
Examples of infinite while loop Example 1: #include<stdio.h>intmain(){intvar=6;while(var>=5){printf("%d",var);var++;}return0;} Infinite loop:var will always have value >=5 so the loop would never end. Example 2: #include<stdio.h>intmain(){intvar=5;while(var<=10){printf("%d...
//for loop for displaying star for(j = 1; j <= i; j++) printf("* "); // ending line after each row printf("\n"); } return 0; } Output: Example 8: Program in C to enter the number of rows to print. In the following program, the user can enter the number of rows to ...
