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)<\/p>\n\n\n\n

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

To print a single line of 97 asterisks using a for<\/code> loop in C, with only the variable k<\/code> declared, you can write:<\/p>\n\n\n\n

for (k = 0; k < 97; k++) {\n    printf(\"*\");\n}\nprintf(\"\\n\");<\/code><\/pre>\n\n\n\n
Explanation:<\/strong><\/p>\n\n\n\n
    \n
  1. Initialization (k = 0;<\/code>)<\/strong>: he loop starts by setting k<\/code> to 0. This initialization ensures that counting begins from 0, which is standard in C since array indices and many loops start from 0.<\/li>\n\n\n\n
  2. Condition (k < 97;<\/code>)<\/strong>: he loop continues to execute as long as k<\/code> is less than 97. Since k<\/code> starts at 0, the loop will execute 97 times (from 0 to 96).<\/li>\n\n\n\n
  3. Increment (k++<\/code>)<\/strong>: fter each iteration, k<\/code> is incremented by 1. This incrementation moves the loop towards its termination condition.<\/li>\n\n\n\n
  4. Loop Body (printf(\"*\");<\/code>)<\/strong>: ithin the loop, printf(\"*\");<\/code> outputs a single asterisk without a newline character. This function call is executed 97 times, resulting in 97 consecutive asterisks on the same line.<\/li>\n\n\n\n
  5. Final printf(\"\\n\");<\/code><\/strong>: fter the loop concludes, printf(\"\\n\");<\/code> 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:<\/strong><\/li>\n<\/ol>\n\n\n\n
      \n
    • Variable Usage<\/strong>: he problem specifies using only the variable k<\/code>. In this solution, k<\/code> serves as the loop counter, and no additional variables are introduced.<\/li>\n\n\n\n
    • Loop Execution Count<\/strong>: tarting k<\/code> at 0 and looping while k<\/code> is less than 97 ensures the loop runs exactly 97 times. This approach leverages zero-based counting, which is idiomatic in C programming.<\/li>\n\n\n\n
    • Output Function<\/strong>: he printf<\/code> function is used for output. By omitting the newline character (\\n<\/code>) in the first printf<\/code> call, all asterisks are printed on the same line. The subsequent printf(\"\\n\");<\/code> 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<\/code> loop and adheres to the constraint of using only the variable k<\/code>.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
