Given an int variable k that has already been declared, use a for loop to print a single line consisting of 97 asterisks

Given an int variable k that has already been declared, use a for loop to print a single line consisting of 97 asterisks. Use no variables other than k. (Please use C standard)

The Correct Answer and Explanation is :

To print a single line of 97 asterisks using a for loop in C, with only the variable k declared, you can write:

for (k = 0; k < 97; k++) {
    printf("*");
}
printf("\n");

Explanation:

1. Initialization (k = 0;): he loop starts by setting k to 0. This initialization ensures that counting begins from 0, which is standard in C since array indices and many loops start from 0.
2. Condition (k < 97;): he loop continues to execute as long as k is less than 97. Since k starts at 0, the loop will execute 97 times (from 0 to 96).
3. Increment (k++): fter each iteration, k is incremented by 1. This incrementation moves the loop towards its termination condition.
4. Loop Body (printf("*");): ithin the loop, printf("*"); outputs a single asterisk without a newline character. This function call is executed 97 times, resulting in 97 consecutive asterisks on the same line.
5. Final printf("\n");: fter the loop concludes, printf("\n"); is called to move the cursor to the next line. This ensures that any subsequent output appears on a new line, maintaining proper formatting.
   Key Considerations:

• Variable Usage: he problem specifies using only the variable k. In this solution, k serves as the loop counter, and no additional variables are introduced.
• Loop Execution Count: tarting k at 0 and looping while k is less than 97 ensures the loop runs exactly 97 times. This approach leverages zero-based counting, which is idiomatic in C programming.
• Output Function: he printf function is used for output. By omitting the newline character (\n) in the first printf call, all asterisks are printed on the same line. The subsequent printf("\n"); ensures the output cursor moves to the next line after printing the asterisks.
  his method efficiently prints a line of 97 asterisks using a for loop and adheres to the constraint of using only the variable k.
