c Language rhombus output program

I have to print out the diamond as it is on that red square screen, but I can't find a solution. I don't know how to organize the code, so I ask. Please also upload the pictures on the screen. https://photos.google.com/photo/AF1QipPSnJLXc6uK4sD2lK1raU64lFt_BAjyi61HmTy-
