An array is a type of data structure that stores a fixed-size of a homogeneous collection of data. For example if a is an array of integers with three elements such that a = 1 a = 2 a = 3 Then on reversing the We shall use a loop and sum up all values of the array. char *function( void ) { static char word[100]; scanf( "%s", word ); // no & operator here return word; // return char * } Declaring the array as static means it exists over the lifetime of the program, not just that function. Program to calculate sum of array in C - This program should give an insight of how to parse (read) array. Second point to remember is that C does not advocate to return the address of a local variable to outside of the function, so you would have to define the local variable as static variable. 1.

Following are some correct ways of returning array: Using Dynamically Allocated Array : Dynamically allocated memory (allocated using new or malloc()) remains their until we … However, you can return a pointer to an array by specifying the array's name without an index. Since the program control comes back to the main() function, and all the variables in a stack are freed. no duplicates in array. We can pass array to a function in the following way and assign value to it: void setMarks(int marks_array []){ for(int i=0;i #include /* This function returns an array of N even numbers */ int* getEvenNumbers(int N){ /* Declaration of a static local integer array */ static int evenNumberArray[100]; int i, even = 2; for(i=0; i /** * Function to return an array … An array in C or C++ is a collection of items stored at contiguous memory locations and elements can be accessed randomly using indices of an array.
