Explanation / Answer

Question 1:

#include<stdio.h>

int main()
{
int i;

char c;
FILE *fp1; //Initialisation of file pointer

fp1=fopen("input file data.txt","r"); //Reading the file input file data.txt
do
{
c=getc(fp1); //Scanning each character
printf("%c",c); // Printing on console
}while(c!=' '); // Condition for end of line
fclose(fp1); // Closing the file
return 0;
}

Question 2:

#include<stdio.h>

int main()
{
int i;
char name[20],studentid[10];
float score1,score2,score3;
FILE *fp1; //Initialisation of file pointer
printf("Enter the name of the student"); // Taking inputs from the console
scanf("%s",&name);
printf("Enter the ID of the student");
scanf("%s",&studentid);
printf("Enter the score1 of the student");
scanf("%f",&score1);
printf("Enter the score2 of the student");
scanf("%f",&score2);
printf("Enter the score3 of the student");
scanf("%f",&score3);
fp1=fopen("student grade.txt","w");
fprintf(fp1,"%s-%s-%f-%f-%f",name,studentid,score1,score2,score3); // Writing into the file student grade.txt
fclose(fp1); // Closing the file

return 0;
}

Question 3:

#include<stdio.h>

int main()
{
int i;
char c;
FILE *fp1; //Initialisation of file pointer

fp1=fopen("input.txt","r"); //Reading the file input.txt
do
{
c=getc(fp1); //Scanning each character
printf("%c",c); // Printing each character on console
}while(c!=EOF); //condition for checking end of the file
printf(" End of the file input.txt");
fclose(fp1); //closing the file input .txt
return 0;
