"Size s p" typically refers to petite sizing, which is designed for people of shorter height. It is a smaller size range that is specifically proportioned for shorter torsos and inseams.

In a letter, "P. S." means "Post Script."

P. Size has written: 'Lithium D cell study' -- subject(s): Lithium cells

S-P interval means the integer minus the integer. The difference times nine.
The mean of a proportion, p, is X/n; where X is the number of instances & n is the sample size; and its standard deviation is sqrt[p(1-p)]
C-style arrays can be used as data members, both as fixed-size arrays or as dynamic arrays. The following examples demonstrate how they could be used as one-dimensional data members. class a { private: int b[10] {0}; // in-class initialisation (all elements zero). public: int& operator[] (unsigned index) { if (index>=10) throw std::range_error(); return b[index]; } }; class c { public: c (unsigned sz=10): size(sz), p (size?new int[size]:nullptr) { memset (p, 0, size); } c (const s& _s): size(_s.size), p (size?new int[size]:nullptr) { if (size) memcpy (p, _s.p, size); } c (s&& _s): size(_s.size), p (_s.p) { _s.p=nullptr; } // swap resources c& operator= (const s& _s) { if (p) delete [] p; size = _s.size; p = (size?new int[size]:nullptr); if (size) memcpy (p, _s.p, size); } c& operator= (s&& _s) { size = _s.size; p = _s.p; _s.p=nullptr; } // swap resources ~c() { if (p) delete [] p; } int& operator[] (unsigned index) { if (index>=size) throw std::range_error(); return p[index]; } private: unsigned size {0}; int* p {nullptr}; }; A much simpler approach would be to use std::array<int> and std::vector<int> instead of primitive C-style arrays.
P is a permutation. It is asking for the numbers in the ()'s after it. For exapmle, P(6,4) is 6x5x4 which is 120.
