Code: int i = 1; while(i <= 5) { printf(“%d “, i); i++; } Answer: The while loop can be converted to a for loop by initializing i, specifying the loop condition, and updating i in the for statement. Here’s the converted for loop: for(int i = 1; i <= 5; i++) { printf(“%d “, … Read more
Code: int i = 1; while(i <= 5) { printf(“%d “, i); i–; } Answer: The code will cause an infinite loop because the condition i <= 5 is always true, and i– causes i to decrease, not increase. Since i starts at 1 and keeps decreasing, it will never reach a point where it … Read more
Code: int x = 10; while(x > 0) { printf(“%d “, x); x -= 3; } Answer: The loop starts with x = 10. In each iteration, the value of x is decremented by 3. The loop will print the value of x before it is decremented. The loop will continue as long as x … Read more
The break and continue statements are used to control the flow of execution in loops, but they serve different purposes: break: This statement is used to exit a loop completely, terminating it regardless of whether the loop’s condition has been satisfied. It is often used when a certain condition is met, and there’s no need … Read more
While loop: The while loop continues executing the block of code as long as the condition remains true. The condition is evaluated before entering the loop, so if it’s false initially, the code inside the loop may not execute at all. Syntax: while(condition) { // code to execute } Example: int i = 0; while(i … Read more
A looping structure is used to execute a block of code repeatedly based on a certain condition. It allows you to repeat operations without needing to write the same code multiple times. Looping structures help in automating repetitive tasks efficiently. A for loop is generally used when the number of iterations is known beforehand. It … Read more
int k; for(k = 25; k > 0; k = k – 3) printf(“\n%d”, k); To convert this for loop into a while loop: int k = 25; while(k > 0) { printf(“\n%d”, k); k = k – 3; } Related Questions: Differentiate between for loop and while loop. Differentiate between while loop and do-while … Read more
Code: int k, a; a = 3; k = 1; while(k < 10) printf(“\n%f AM %f”, k, k*a-1); k = k + 2; Error 1: The printf statement has a format specifier %f (float), but the variables k and k*a-1 are integers. This will cause incorrect output or undefined behavior. Fix: Change %f to %d … Read more
Code: int n; for(n=30; n>=10; n=n-5) printf(“%d\n”, n); This for loop starts with n = 30 and decreases n by 5 until n is less than 10. The loop will print the value of n on each iteration. Output: 30 25 20 15 10 Related Questions: What will be the output of the following code? … Read more
Code: int k; for(k=1; k<=5; k++) printf(“\nI am a student”); printf(“\nGOOD BYE”); The for loop will print “I am a student” five times because the loop runs from k = 1 to k = 5. After the loop finishes, printf(“\nGOOD BYE”); will print “GOOD BYE” once, outside the loop. Output: I am a student I … Read more
