Question
What is the value of integer variable b, if we find programming statement like b=printf(“ES-CS201”);
Solution
In C programming, the printf() function returns the number of characters successfully written on the output. So, if we have a statement like b=printf("ES-CS201");, the value of b will be 8, because "ES-CS201" is 8 characters long.
Here are the steps:
- The printf() function is called with the string "ES-CS201" as an argument.
- The string "ES-CS201" is printed to the standard output (usually your screen).
- The printf() function returns the number of characters in the string that were successfully written. In this case, it's 8 characters: E, S, -, C, S, 2, 0, 1.
- This return value (8) is then assigned to the variable b.
So, the value of b after this statement is executed will be 8.
