WebEnter base and exponent respectively: 2.3 4.5 2.3^4.5 = 42.44. In this program, we have used the pow () function to calculate the power of a number. Notice that we have included the cmath header file in order to use the pow () function. We take the base and exponent from the user. We then use the pow () function to calculate the power. WebThe function calls pow(unqualified) once for each element in both xand y; If either is a single Tvalue, it is used for all calls. This function overloads cmath's pow. Parameters x valarrayor element with the bases for the power operations. y valarrayor element with the exponents for the power operations. perry mattfeld as melWebC++11 Header provides a type-generic macro version of this function. Parameters x Value whose square root is computed. If the argument is negative, a domain error occurs. Return Value Square root of x.
