Some solutions to use output parameter and copy the value of the array into the value of this output parameter array. Other solution to pass an array and use it inside the function. 一些解决方案是使用数组作为输出参数,并将值复制到这个参数。 Others to allocate the array inside the function and...
Use Pointer to Pointer Notation to Return 2D Array From Function in C++ As an alternative, we can use a pointer to pointer notation to return the array from the function. This method has an advantage over others if the objects to be returned are allocated dynamically. Usually, one should mo...

met. If both conditions are met, the corresponding element from the third array gets into the final array (e.g. 1*1*C2 = 10). So, the result of multiplication is this array: {10;0;0;30;0;0;0;0}. Finally, the SUM function adds up the array's elements and return a result of...
