Expression Must Be Integral Or Unscoped Enum Type In C++?

Hi, I am trying to calculate the distance between two points, by using Pythagorean Theorem and the x,y coordinates of two points. However, I have the following issue in line 14: "Expression must have integral or enum type".I have been working on C++ for a while now, but this error message "Expression must have integral or unscoped enum type"? showed up and I do...The goal is to use CUDA to calculate the integral of sqrt(4 - x * x) from 0 to 2 using the trapezoidal rule. Main asks the user for how many partitions to use in the calculation then allocates the space on the GPU. expression must have arithmetic or unscoped enum type.expression must have integral or unscoped enum type?IntelliSense: expression must have integral or unscoped enum type c:\Work\Tradex\Source\Tradex.Connectivity.Rithmic\RithmicConnector.cpp 269 32 Tradex.Connectivity.Rithmic.

How do I fix "Expression must have integral or unscoped enum..."

How c++ expression can have integral or unscoped type? expression must have a constant value c++. Problem: Hello all, How to declare an array properly in c/c++? I am a new student of c++ and I am trying to declare two-dimensional arrays in my program.But there is an error that says: "Expression must have integral or enum type" and also shows that the left hand side of % has a double and right hand side has a constant double.It's what it says: the expression must have integral or unscoped type. The line and column number points you to the % operation. This is an integer modulo operation, which requires integers.Both t and n are pointers to D3DXVECTOR3 so you must dereference them to be able to do the subtraction. Where did you get the code from? I'm personaly quite confused about the second part of the line.

Need Help With 2D Arrays And Out Putting Decimal Points - Homework.1) Declares an unscoped enumeration type whose underlying type is not fixed (in this case, the underlying type is an implementation-defined integral 3) Opaque enum declaration for an unscoped enumeration must specify the name and the underlying type. Each enumerator becomes a named...You can only use integral types (integer, enum, char etc. which are convertible to integral value), or any expression that evaluates to an integral type … Oct 04, 2013 · Error: expression must have integral or unscoped enum type.

I want to get the size of the array from the person, but when I'm the use of (drift *temp = new flow[dimension];), I were given an error "expression must have integral or unscoped enum type." When I input the number, it running effectively up till to the variability number. After that, start from deviation to the usual deviation, the calculation all tousled.

If I take advantage of int for the 'dimension' and keep the 'temp' as waft, it gave me other error.

How can I repair this?
