Question

What is the output? float x = 5.9999; printf("%.2f", x);

a. 5.99
b. 5
c. 6
d. 6.00
e. 5.9

Answer 1

The code will output 6.00, as the %.2f format specifier in printf rounds the float to two decimal places.

Step-by-step explanation:

The output of the given code snippet, float x = 5.9999; printf("%.2f", x);, will be 6.00. The format specifier %.2f tells the printf function to round the float value to two decimal places. Since the third decimal place is 9, the value is rounded up, resulting in an output of 6.00. he format specifier "%.2f" in the printf function instructs it to display the floating-point value with exactly two decimal places. In this case, the original value of x is 5.9999, and due to rounding rules, the third decimal place, which is 9, leads to rounding up. Consequently, the final output is 6.00, reflecting the rounded value of the floating-point number to two decimal places. This behavior ensures precision in the displayed output, especially when working with numerical values in programming.
