Охххymiron We are not here to write your Code. Do self and show your attempts if you are facing any problem.

Finding the sum of all elements in a given row/column requires a simple iteration over the matrix. If you need help with the code, please provide what you have done so far.

Охххymiron Just to reiterate what has been stated, "Please provide what you have done so far". I am not here to write your code, a little work on your side is required. Try to solve it on your own, and if you are stuck, then you can post the code here and we will help you with it.

There were some syntactic errors in the code, I also simplified the initialization a bit and added a variable to control how many rows are summed up. This is the fixed code for now: https://code.sololearn.com/cme3G6mID8T7/?ref=app

#include <iostream> #include <cstdlib> #include <ctime> /* run this program using the con using namespace std; int main() { int n,m, sum=0; srand(time(NULL)); cin>>m; cin>>n; int**mas ; mas=new int*[m]; for (int i=0;i<m;i++) {mas[i]=new int[n];} for(int i-0;i<m;i++) {for(int j=0;j<n;j++) {mas[i][j]= rand()%10; cout<<mas[i][j]<<" "; } cout<<endl;} for(int i-0;i<m;i++) {for (int j=0;j<n;j++) {if(i<3) { sum=sum+mas[i]j];} } } cout<<sum<<" "; return 0; }
