Arrays

Ok their are two things i'am having trouble with. One I must give a simple explanation what the relation between arrays and pointers. Now i know why pointers maybe be helpful in arrays, but a relation between the two? I must be reading into this too much


second, Given the array int a[3][4], describe how to store in the second element of the second array the value 5 uisng pointers in all possbie ways. Here is a problem of mine i'am facing. I know how to move between elemtns in a one dimesional array using pointers but a two??


thank for for any help
