Explanation:
Some variable naming conventions include;
1) Variable should begin with either a letter or an underscore.
2) Variables having multiple words should have the first letter of every word after the first word, capitalized. This is the camelCase style.
3) variables should not be named after any of the inbuilt keywords except on special operations to override the original function of such keyword.
4) variable names are case-sensitive.
The importance of following these conventions is to maintain readability and consistency of code. Failure to follow these conventions may lead to chaotic codes, bugs and inefficient performance.
Answer:
#include <iostream>
#include <cstdlib>
using namespace std;
int m, n;
void transpose(int matrix[]){
int transp[m][n];
for (int i = 0; i < n; i++){
for (int j = 0; j < m; j++){
transp[j][i] = matrix[i][j];
cout<< transp[j][i]<< " ";
}
cout<< "\n";
}
}
int main(){
cout<< "Enter the value for n: ";
cin>> n;
cout>> "Enter the value for m: ";
cin>> m;
int mymatrix[n][m];
for (int i = 0; i < n; i++){
for (int j = 0; j < m; j++){
mymatrix[i][j] = (rand() % 50);
}
}
transpose(mymatrix);
}
Explanation:
The C source code defined a void transpose function that accepts a matrix or a two-dimensional array and prints the transpose on the screen. The program gets user input for the row (n) and column (m) length of the arrays. The C standard library function rand() is used to assign random numbers to the array items.
