//reading data from a data file
#include<stdio.h>
#include<conio.h>
int main()
{
FILE *k;                                     //  pointer for file declaration
char name[30],choice;                        //identifier declaration
int roll;                                          //       "             "
float per;
k=fopen("student.txt","r");          //opening of file in write mode
printf("records are\n");
while((fscanf(k,"%d %f %s",&roll,&per,name))!=EOF)//inputs goes until the file ends(End of File)
{
printf("roll=%d per=%f name=%s\n",roll,per,name);   //printing on screen
}
