Question

A program contains the following declarations and initial assignments.

int i=8, j=5;

double x =0.005, y=-0.1;

char c=’c’, d=’d’;

Determine the value of the following expressions which involve the use of library functions:

abs(1-2*j); log(exp(x)); toupper(d)

• A. 2; 0.005; D
• B. 1; 0.005; D
• C. 2; 0.005; E
• D. 1; 0.005; e

Answer 1

abs(i-2*j) This function returns the absolute value =2

log(exp(x)) =ln(e^x) =.005

toupper(d) letter to be converted to uppercase=D

So option A is correct.
