Question

What is the difference between function template and template function?

Answer 1

The function generated by the compiler from function template(generic function) for specified data type is known as template function. Example: The below code is called function template as it is template for a function.

template
T doubleVal(T a){
  return a+a;
 }
int main(){
  cout<(5)<

When we compile this code compiler will write a function for int by taking reference from template function. That function is known as template function.
