}3.4.6.Compute the greatest common divisor of 1986 and 343.
3.5 Mathematical library.........................
Table 3.5.1 lists functions of the C++ mathematical library. To use these
functions, the associated header file must be included at the beginning of the
program by stating:
#include<cmath>For example, to compute the exponential of a numbera, we write:#include<cmath>float a = 2.3;
float b = exp(a);Equally well, we can write
double b = exp(2.3);
