The program has following issues: Array indexing is wrong : Array is of size 5 starting from 0 , you can use only till a[4] , but for scanf() , it tries to read value as &a[5]. No use of for loop when you are using hard coded index a[1],a[2],etc. Instead the below code will … Read more
#define SQUARE(x) (x*x) may results in a negative value, e.g. cout << SQUARE(-1-2) << endl; gets resolved in -1 – 2*-1 – 2 and produces -1. It is much better to avoid macros, but if you use this one, make it #define SQUARE(x) ((x)*(x)) solved Why this piece is outputting NAN (Not a Number)?
