Instructions: You are strictly not allowed to use anything other than pointers and dynamic memory. One function should perform one functionality only. Task 1 Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task. Row wise Sum Column wise Sum Diagonal wise Sum Example data.txt 4 5 1.6 10.2 33.7 99 20.5 3 44 50 96.1 2 8 9 4 74 50 99 19.1 Output: Sum row wise: 165, 191, 17, 242.1 Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5 Sum diagonal wise: Not Possible Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.
1. in C: write program with struct student, that has name and age. Declare a pointer to struct student *ptr, but don't assign a value to it. Then, print ptr->age. 2. What GDB commands would you use to identify the error that occurs?
Please due in C++ If possible can explain what should I put in StudentInfo.h file what in StudentInfo.c Thank you
use Advanced C++ techniques, containers and features to refactor the C/C++ algorithm. The purpose is toreplace appropriate declarations and code segments with Advanced C++ declarations and code. * Replace all arrays with appropriate STL containers. * Use STL algorithms to REPLACE existing logic where appropriate. * Use smart and move pointers where pointers are needed. * Use lambda expressions where appropriate. * Use C++ style casting when needed. * Look for opportunities where tuples could be used. * The code listing is in C and C++. If you don't understand someof the C code or C functions, please google. If there are logic or syntax problems, please fix. int Algorithm(int a[], int x, int y) { int p, i, j = x; p = y; for(int i=x; i < y; i++) { if(a[i] < a[p]) { swap(&a[i], &a[j]); j++; } } swap(&a[p], &a[j]); return j;}
