Need some help with a project please!!

hey everyone. been trying to figure out this assignment but cant quit get it.
what i need to do is open a given txt file and read it its contents and place them into a vector.
the practice file is this:
9 John 3 Jane 7 Tom 2 Sam
6 Tom 1 Nicole 5 Tom
4 Jane 8 Ben

i need to place the names in the file into a vector in the order of the number in front of them. so it should look like this when i cout the vector contents:
nicole
sam
jane
jane
tom
tom
tom
ben
john

the code that i have written so far does this:
9
John
3
Jane
7
Tom
2
Sam
6
Tom
1
Nicole
5
Tom
4
Jane
8
Ben

i have counted through the vector and found that there are 9 names in the file. then i created a new vector called "names" that has a size of 9. my idea is to count through the original vector "v" and check at each position of v[i] for the number 1 (which i assigned to the character x). so if v[i] == x then i want the code to take the string after that character, v[i+1] and push that string into the new vector "names" using names.push_back().

the code in bold is where im having trouble. i believe it is because the vector v is in strings and i need to convert it to integers before i can compare my first condition of x < v.size() but i dont know how to do this.

so please help me out if you can understand what im trying to do. haha.

this is my code:

5

I would read the data into a pair of the form <int,string> then I would insert this into a vector. The you can either use the std's built in sort function or make use of your own.
