Simple Monitoring Console

Hi All,

Find the below simple user console program what i have written in "C" @Linux. It might be helpful to you in monitoring.

Here is the snippet of code, for your reference.

#include"stdio.h"
#include"stdlib.h"
#include"ncurses.h"
#include"string.h"
#include "sys/types.h"
#include "unistd.h"
#include "sys/wait.h"
void init()
{
int i,j;
for(i=1;i<=25;i++)
{
printw("\n%3d-|",50-i*2);
}
printw("\n%3s"," ");
for(j=1;j<=32;j++)
{
printw("%3s","-");
}
printw("  ");
printw("\n\n\n");
printw("%5s"," ");
for(j=1;j<=94;j++)
{
printw("=");
}
printw("\n");
printw("%60s","TOP 10 CPU PROCESSES");
printw("\n");
printw("%5s"," ");
for(j=1;j<=94;j++)
printw("-");
mvprintw(1,110,"");
for(j=1;j<=40;j++)
printw("=");
printw("\n");
mvprintw(2,123,"PRIMARY MEMORY");
mvprintw(3,110,"");
for(j=1;j<=40;j++)
printw("-");
refresh();
}

main()

{

fgets(info,50,fp);
sscanf(info,"%f, %f, %f",&f1,&f2,&f3);
mvprintw((50-(int)f1)/2,j,"%3s","*");
if((int)f1>=10)

{

}
