newbie question

i have two vectors i am trying to compare the first is a string vector and the other is a char vector. i am trying to find for example the word hello in the grid vector and i can find the fist char but i dont know how to move or set up a loop to check all the possible directions for the next char in the string. here is a bit of my code. Once the first char is found i need to find the next which the next char could be in 9 possible directions.

-String Vector-
01234
0hello 1apple
2car
3me 4men
5ran
6woman

-Grid Vector-
01234
0cenad
1aatps
2rnrpj
3hello
4wmneo

for(int i=0; i < GridVector.size(); i++)
{
for(int j=0; j < GridVector.size(); j++)
{
if(StringVector[0][0] == GridVector[i][j])
{

{
}
}
