Question

Write a user-defined function swap_row(int ARR[ ] [3] , int R, int C) in C++ to swap the first row values with the last row values: e.g. if the content of the array is:

Then after function call, the content of the array should be.

Answer 1

void swap_row(int ARR[ ][3], int R, int C) 

{ 

for(int i=0; i<R; i++)

for(int j=0: j<C; j++) 

{ 

int temp=ARR[i][j]: 

ARR[i][j]=ARR[R-1][j]; 

ARR[R-1][j]=temp; 

}

 }
