3. Passing a Multi-dimensional array to a function Here again, we will only pass the name of the array as argument. #include<stdio.h>voiddisplayArray(int arr[3][3]);intmain(){int arr[3][3],i,j;printf("Please enter 9 numbers for the array: \n");for(i=0;i<3;++i){for(j...
functions that belong to a struct have an extra first argument with a pointer to the struct. where a function returns UDT (user defined type) by value some compilers complain so the function is generated accepting a pointer to the UDT type as the first argument (or second if belongs to a...
pass a value using call by reference, theaddressof the arguments are passed onto the formal parameters.
