An infinite loop is a loop that never terminates because its condition always evaluates to true, or there’s no exit condition defined. It continues to execute indefinitely until it is manually interrupted or the program is terminated. Example of an infinite loop: while(1) { printf(“This is an infinite loop\n”); } The condition 1 is always … Read more
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
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
The while and do-while loops are similar in functionality, but they differ in the point at which the condition is tested: While loop: The condition is evaluated before the loop body is executed. If the condition is false from the start, the loop body will not execute even once. Example: int i = 0; while(i … Read more
