I am getting possible use of cChoice before definition and declaration terminated incorrectly
#include<stdio.h>
#include<string.h>
#include<conio.h>
#include<iostream.h>
#include<stdlib.h>

void main()
{
char userId[10],passwrd[10];
char uoid[] = "MIS",opasswrd[] = "123";
int chances = 3;
char cChoice;

while (chances)
{
printf("Enter User ID -> ");
scanf("%s", userId);
printf("\n");
printf("Enter Your Password -> ");
scanf("%s", passwrd);

if (strcmp(uoid, userId) == 0 && strcmp(passwrd, opasswrd) == 0)
{
printf("Correct User Id And Password\n");
break;
}
else
{
printf("Invalid User Id And Password\n\n");
chances--;

if(!chances)
{
printf("You have no more chances...\n");
printf("Do you want to register y/n -> ");

printf("\n");

if(cChoice=='Y'||cChoice=='y')
{
printf("Enter your new ID -> ");
scanf("%s",uoid);
printf("Enter your new PW -> ");
scanf("%s",opasswrd);

chances = 3;
}
}
}
}

clrscr();


}
{
char choice;
char c[50];
char id[50];
char age[50];
char last[100];
char first[100];
char dep[50];
char add[50];

b:
clrscr();
printf("=====PROGRAM MENU=====");
printf("\n\n[1] = CIRCLE AREA");
printf("\n[2] = RECTANGLE AREA");
printf("\n[3] = TRIANGLE AREA");
printf("\n[4] = LAST GRADE");
printf("\n[5] = LETTER GRADE");
printf("\n[6] = FACTORIAL");
printf("\n[7] = PRINTING");
printf("\n[8] = Exit Program");
printf("\n\nChoice : ");
scanf("%d",&choice);
switch (choice)
{
case 1:
clrscr();
FILE * f;

f=fopen("test.txt","r+");
if(f==NULL){
printf("No Database");
exit(1);
}

getch();

Line 7: main() must be type int

Line 12: cChoice is an uninitialized variable (garbage).

Line 39: You test cChoice, but cChoice is an uninitialized variable.

Line 54-55: What are the {} for?

Line 89: You're missing a } terminating the switch statement.

PLEASE USE CODE TAGS (the <> formatting button) when posting code.

Lines 55-57: There is still no reason for the }{ here.

Line 91: You're still missing a } for the switch statement. Note that the } at line 90 terminates the if statement, not the switch statement.

This compiles with only warnings:
