// in function modifyArray, "b" points to the original array "a" in memory void modifyArray( int b[], int sizeOfArray ) { // multiply each array element by 2 for ( int k = 0 ; k < sizeOfArray ; ++k ) b[ k ] *= 2; } // end function modifyArray // in function modif...
In Go, arrays can be passed to functions as arguments. However, when an array is passed to a function, it is passed by value, meaning a copy of the array is made. To modify the original array, a pointer or slice should be used. Passing an Array by Value By default, Go passes arra...
When passing an array to a function, normally the array size is passed as well, so the function can process the specific number of elements in the array. Otherwise, we would need to build this knowledge into the called function itself or, worse yet, place the array size in a global ...

I'm coding on a KL46Z Mcu, using CW10.6/PEx IDE plus MQXLite and I have some troubles with double pointer accesses. In fact I'm passing a 2D array to a function. When I read the double pointer value, there is a Cpu Hard Fault. Basically my func...
