Question

What is the output when the following segment of ‘C’ code is executed? void main() { float a = 123.456; printf("%.2f, %7.3f, %12e", a, a, a); }

Accepted Answer

Correct answer: B — %.2f rounds 123.456 to 2 decimal places, giving 123.46. %7.3f prints with a minimum total width of 7 characters and 3 decimal places, matching the length of 123.456 perfectly. %12e prints in scientific notation with 6 default decimal places, padded with spaces to fit 12 characters: 1.234560e+02. Thus, the correct option is B.
