fahrishb (30)
Hi everyone i'm writing a program that reads the name of the restaurant and the number of visitors of the restaurant. the goal of the program is to print the name of the restaurant with the most number of visitors (sum up all the number of visitor). I believe i am close to getting the answer, but i am stuck and i cant figure it out anymore. If any of you are willing to help me, i will appreciate that very much. thank you.

here is the sample data that i am trying to work on

how to add up the likes with the same restaurant
It whould be much simplier with a map. But on the othe hand you already found the pos on line 43.
Use it: likes[pos] += like;

Remove line 33


By the way: you really don't need a pointer to the strings (string*). Simply use string like a built in variable (string)
