( Someone skilled in Fortan )

I wrote up some code in C++ and I am having a bit of a hard time translating it into Fortan 90 as I am a beginner CS student. I have do all of the work below. I simply ask if someone can translate it to Fortan 90. I understand logic fully in C++ so I do not need an explanation just help changing it into Fortran 90. Thanks!

int i, j, k = 0;

int n = 3; //number of observations

float x[3] = { 3, 4, 5 }; // stores x data points float y[3][3] = { {5, 10, 1}, {0,0,0}, {0,0,0} }; // divided difference table. First col is y value

// compute newton's divided difference formula and store it array for (i = 1; i < n; i++) { k = i; for (j = 0; j
