SUMMARY
The discussion focuses on generating random numbers from an array in C++. The user initially seeks assistance for selecting a random number from the array A={1,4,-1,3,-7,2,-14}. The solution provided involves using the srand() function to seed the random number generator with the current time, followed by the rand() function to select an index from the array. The final code snippet shared is: srand(time(NULL)); random = arr[rand() % (sizeof(arr) / sizeof(arr[0]))];
PREREQUISITES
