C - Input and Output

You want to print a table of numbers and their squares using printf. Which code snippet correctly prints the number 4 and its square 16 in the format "4 squared is 16"?

Aprintf("%d squared is %d", 4, 16);

Bprintf("%d squared is %d", "4", "16");

Cprintf("4 squared is 16");

Dprintf("%s squared is %s", 4, 16);

Step-by-Step Solution

Solution:

Step 1: Check format specifiers and arguments
printf("%d squared is %d", 4, 16); uses %d for integers 4 and 16, which matches the data types correctly.
Step 2: Analyze other options for errors
printf("%d squared is %d", "4", "16"); passes strings instead of integers, printf("4 squared is 16"); prints fixed text without variables, printf("%s squared is %s", 4, 16); uses %s for integers which is incorrect.
Final Answer:
printf("%d squared is %d", 4, 16); -> Option A
Quick Check:
Use %d for integers and pass matching arguments [OK]

Quick Trick: Match %d with integers, %s with strings in printf [OK]
