Find the second largest number in a arrary

// Using single loop for finding the second largest number in the array
# include<stdio.h>
# include<stdlib.h>
# define MAX 5
int main()
{
int nLoop;
int nMaximumFirst,nMaximumSecond;
int szArray[MAX];
// to get input
/* Please ignore this loop by direct initalization*/
for(nLoop=0;nLoop<MAX;nLoop++)

{
nMaximumSecond = nMaximumFirst;

}else if(nMaximumSecond < szArray[nLoop])

}

}

}
printf("Maximum first =%d,\nMaximum second = %d\n",nMaximumFirst,nMaximumSecond);

}

OUTPUT:

4
5
3
2
1
Maximum first =5,
Maximum second = 4
