Loop control structure

Loops allow code to repeat execution of statements. There are three main types of loops: for, while, and do-while. A for loop uses a counter variable to control the number of iterations and is best for loops with a known number of repeats. A while loop continuously executes statements as long as a test condition is true. A do-while loop ensures statements execute at least once before checking the condition.

Loop control structure
- 2. Loops : Loops statements are used to repeat the execution of statements.
- 3. Types Of Loops :
- 4. Entry control Loop For Loop While Loop
- 5. For Loop
- 9. Example of for Loop #include <stdio.h> int main() { int n, count, sum=0; printf("Enter the value of n.n"); scanf("%d",&n); for(count=1;count<=n; count++) //for loop terminates if count>n { sum+=count; /* this statement is equivalent to sum=sum+count */ } printf("Sum=%d",sum); return 0;
- 14. /*C program to demonstrate the working of while loop*/ #include <stdio.h> int main() { int number,factorial; printf("Enter a number.n"); scanf("%d",&number); factorial=1; while (number>0) { /* while loop continues until test condition number>0 is true */ factorial=factorial * number; number--; }
- 18. Flow Chart of Do-While Loop
