Sir i wanted to know why are we adding thus if(curr==c) condition every tym

#1

#include
using namespace std;
void spiralprint(int a[][10], int M, int N);
int main()
{
int i,j;
int M,N;
cin>>M>>N;
int a[10][10];
for(i=0;i<M;i++)
{
for(j=0;j<N;j++)
{
cin>>a[i][j];
}
}
spiralprint(a,M,N);
cout<<“END”;
return 0;
}
void spiralprint(int a[][10], int M, int N)
{
int sc=0,sr=0,ec=N-1,er=M-1,i;
int curr=0,c=M*N;
while(sc<=ec&&sr<=er)
{
if(curr==c)
break;
for(i=sr;i<=er;i++)
{
cout<<a[i][sc]<<", “;
curr++;
}
sc++;
if(curr==c)
break;
for(i=sc;i<=ec;i++)
{
cout<<a[er][i]<<”, “;
curr++;
}
er–;
if(curr==c)
break;
for(i=er;i>=sr;i–)
{
cout<<a[i][ec]<<”, “;
curr++;
}
ec–;
if(curr==c)
break;
for(i=ec;i>=sc;i–)
{
cout<<a[sr][i]<<”, ";
curr++;
}
sr++;
if(curr==c)
break;
}
}

Hello @sneha23 in this condition we are checking whether the number of elements are not greater then total number of elements in the array.
total number of elements are m*n.
and everytime we are incrementing the curr for printing every element of the array.
if at any point we find that total elements we have printed is equal to the elements in the array the it will break at that point only.
