Write a program segment (NOT THE ENTIRE PROGRAM) which takes a two dimensional array A, with size N rows and N columns and prints the upper half of the array. Example..this

Complete the function given below:  int square (int x) { // Return square of x } C++ language.

A code for the detection and correction of errors was implemented using the Hamming method, this code was made in c ++. Make the code in Matlab, in such a way that the c ++ code is a base, to be able to develop the algorithm or the error detection and correction program using the Hamming method. The algorithm made in c ++ is shown below so that you can develop it in matlab.   #include <stdio.h> #include <math.h>   int main() {         int a[20], b[20], c[20], d[20], i, k, m, f, n, j, r, p, x, y, z, ch,             key, q, v, sum = 0;         system("clear");         printf("\n Ingresa la longitud de la palabra de datos :");         scanf("%d", &k);         printf("\n Ingresa la palabra de datos: \n");         for (i = 1; i <= k; i++) {                  scanf("%d", &a[i]);         }         m = 1;         while ((k + m + 1) >= pow(2, m)) {                  m++;         }         printf("\n El valor de  m es : %d", m);         n = k + m;         j = 1;         r…
