avector index out of bound issue C++

[AbdulBasee]

vector shortBubbleSort(vector avector){ //the vector for bubble sort bool exchanges = true; int passnum = avector.size(); //while vector size is greater than 0 and exchanges = true while (passnum > 0 && exchanges) { exchanges = false; //loops through vector, exchanging values until it reaches the end of vector. for(int i = 0; i < passnum; i++){ if(avector[i] > avector[i+1]){ exchanges = true; int temp = avector[i]; avector[i] = avector[i+1]; avector[i+1] = temp; } } //subtracts from the passnum variable so that the next passthrough is one less //than the previous, because the largest value has already 'bubbled' all the way up. passnum = passnum - 1; } return avector;

The comparison of avector[i] with avector[i + 1] is going to create an issue when we are comparing the last element. The error will be as follows: "Invalid read of size 4" for avector of size four.
