![You are given the following function moveIndexes, where NR and NC are numerical constants. The function receives as
parameters rp and cp, two pointers to int. The goal of the function is to modify the values pointed by rp and cp as follows: if
rp and cp originally point to the indexes of a certain cell of the matrix, after function invocation they must point to the indexes of
a cell at a distance delta from the original one.
int movelndexes (int M[NR][NC], int *rp, int *cp, int delta) {
int i, j, *p, *p0;
i = *rp;
j = *cp;
if (i<0 || i>=NR || j<0 \[ j>=NC)
return 1; // error

p0 = & (M[] [0]);
p = & (M[i [5]);
