5.1 Function Calls

A function call is a primary expression, usually a function identifier followed by parentheses, that is used to invoke a function. The parentheses contain a (possibly empty) comma-separated list of expressions that are the arguments to the function. The following is an example of a call to the function power , assuming this function is appropriately defined:

main()
{
   .
   .
   .
y = power(x,n);                     /* function call */
}

See Section 6.3.2 for more information on function calls.
