I'm trying to create a function where it allows the user to type in multiple amounts of integers, so if the user wanted to have 3 different storages that hold different integers, the input would look something like this:
1 2 3 4 5 6
97 12 31 2 1 //let's say this is held in variable "a"
1 3 284 3 8 // "b"
2 3 482 3 4 // "c"
2 3 4 2 3 // "d"
99 0 2 3 42 // "e"
Since we don't know what number the user will input every time, I'm not sure how to create a dynamically allocated array that will create an x amount of arrays every time.. I want to be able to access each index of a, b, c, d, e or however many arrays there are.
So far, this is what I have, but I'm having trouble creating the arrays since it's unpredictable. I'm purposely not using vectors because I don't really get how pointers work so I'm trying to play around with it.
1 2 3 4 5 6 7 8 9 10
int length, numbers;
cin >> length;
x = newint[length]
for (int i=0;i<length;i++)
cin >> numbers; //this doesn't work because it only grabs the first line for some reason
x[i] = numbers
If anything seems unclear, please let me know! Thank you!
int **x; //You should probably invest in a better name :P
std::cout << "How many lines of numbers? ";
std::cin >> lines;
x = newint *[lines];
for( int i = 0; i < lines; ++i )
std::cout << "How many numbers is this line? ";
std::cin >> numbers;
x[i] = newint[numbers];
std::cout << "Please enter the numbers separated by spaces: ";
for( int j = 0; j < numbers; ++j )
std::cin >> x[i][j];
for( int i = 0; i < numbers lines; ++i )
I would highly suggest you use a STL container such as a vector though.
