Turn to BASH

[Vmp3]

I know this is an easy and straight forward algorithm and code... but I'm quite useless with Bash and putty.
I've done the code just not in .sh format

#include<stdio.h>
void main()
{
char p[10][5];
int tot=0,wt[10],i,n;
float avg=0;
clrscr();
printf("enter no of processes:");
scanf("%d",&n);
for(i=0;i<n;i++)
{
printf("enter process%d name:\n",i+1);
scanf("%s",&p[i]);
printf("enter process time");
scanf("%d",&pt[i]);
}
 
wt[0]=0;
for(i=1;i<n;i++)
{
wt[i]=wt[i-1]+et[i-1];
tot=tot+wt[i];
}
avg=(float)tot/n;
printf("p_name\t P_time\t w_time\n");
for(i=0;i<n;i++)
printf("%s\t%d\t%d\n",p[i],et[i],wt[i]);
printf("total waiting time=%d\n avg waiting time=%f",tot,avg);
getch();
}

Basically I need to make this code run in putty as a .sh file ... and I rarely use this putty thing so my skills there are extremely limited... help would be appreciated .
