The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

To print a single line consisting of n<\/code> asterisks using a while<\/code> loop in C, you can use the following code:<\/p>\n\n\n\n

#include <stdio.h>\n\nint main() {\n    int n = 5; \/\/ Example positive value for n\n    while (n > 0) {\n        printf(\"*\");\n        n--;\n    }\n    printf(\"\\n\"); \/\/ Move to the next line after printing all asterisks\n    return 0;\n}<\/code><\/pre>\n\n\n\n
Explanation:<\/strong><\/p>\n\n\n\n
    \n
  1. Initialization<\/strong>: he variable n<\/code> is initialized to a positive integer value, representing the number of asterisks to be printed. In this example, n<\/code> is set to 5.<\/li>\n\n\n\n
  2. While Loop Condition<\/strong>: he while<\/code> loop continues to execute as long as n<\/code> is greater than 0. This ensures that the loop runs exactly n<\/code> times.<\/li>\n\n\n\n
  3. Printing Asterisks<\/strong>: ithin the loop, printf(\"*\");<\/code> outputs a single asterisk without moving to a new line.<\/li>\n\n\n\n
  4. Decrementing n<\/code><\/strong>: fter printing an asterisk, n<\/code> is decremented by 1 using n--;<\/code>. This reduces the value of n<\/code> by one in each iteration, bringing it closer to the loop termination condition.<\/li>\n\n\n\n
  5. Loop Termination<\/strong>: nce n<\/code> reaches 0, the while<\/code> loop condition n > 0<\/code> becomes false, and the loop exits.<\/li>\n\n\n\n
  6. Newline Character<\/strong>: fter exiting the loop, printf(\"\\n\");<\/code> is used to move the cursor to the next line. This is optional but ensures that any subsequent output starts on a new line.
    Key Points:<\/strong><\/li>\n<\/ol>\n\n\n\n
      \n
    • Single Variable Usage<\/strong>: he task specifies using no variables other than n<\/code>. In this solution, n<\/code> serves both as the loop counter and the determinant of the number of asterisks to print.<\/li>\n\n\n\n
    • Loop Mechanics<\/strong>: he while<\/code> loop is appropriate here because the number of iterations is determined by the initial value of n<\/code>. The loop decrements n<\/code> with each iteration until it reaches zero, ensuring that exactly n<\/code> asterisks are printed.<\/li>\n\n\n\n
    • Output Control<\/strong>: y not including a newline character within the loop’s printf<\/code> statement, all asterisks are printed on the same line. The newline character is added after the loop to finalize the output line.
      his approach efficiently prints a specified number of asterisks in a single line using a while<\/code> loop and adheres to the constraint of using only the variable n<\/code>.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
