Problem with vector push_back

shooninjo (44)
Hello. I am trying to get the locations of certain letters from a string into a vector. However there is something wrong. I can't seem to get the right number into the vector as every dimension is still at 0. What i'm i doing wrong?

The code is: 
1
2
3
4
5
6
7
8

push_back adds to the end of the vector. Since the vector was size 20 to start with, you're adding them after those positions.
