initialize array in c++ code example
Example 1: initialize an array in c++
int nums[100] = {0}; // initiallize all values to 0
int nums[5] = {1,2,3,4,5};
// type name[size] = {values};
Example 2: c++ initialise array
int nCount[] = {1, 2, 3, 4, 5};
Example 3: c++ initialize array
int arr[3] = {1, 5, 4};
Example 4: initialize array c++
int foo [5];
Example 5: how to initialize array with new in c++
int* a = NULL; // Pointer to int, initialize to nothing.
int n; // Size needed for array
cin >> n; // Read in the size
a = new int[n]; // Allocate n ints and save ptr in a.
for (int i=0; i<n; i++) {
a[i] = 0; // Initialize all elements to zero.
}
. . . // Use a as a normal array
delete [] a; // When done, free memory pointed to by a.
a = NULL; // Clear a to prevent using invalid memory reference.
