terminal.
Ans:
#include
#include<conio.h>
void main()
{
FILE *fp;
char c;
clrscr();
fp=fopen("myfile","w");
printf("Type any string and press cny-z
for terminate\n");
while((c=getchar())!=EOF)
{
putc(c,fp);
}
fclose(fp);
fp=fopen("myfile","r");
while((c=getc(fp))!=EOF)
{
printf("%c",c);
}
fclose(fp);
getch();
}
Q Write a
program to create one integer value contained file. From this create two
another files one for odd and one for even.
Ans:
#include
#include<conio.h>
#include
void main()
{
FILE *fp,*ep,*op;
char c;
int i,no;
clrscr();
fp=fopen("ifile","w");
for(i=0;i<5 i="" span="">
{
printf("Give number %d:",i+1);
scanf("%d",&no);
putw(no,fp);
}
fclose(fp);
fp=fopen("ifile","r");
ep=fopen("efile","w");
op=fopen("ofile","w");
while((no=getw(fp)!=EOF))
{
if(no%2==0)
putw(no,ep);
else
putw(no,op);
}
fclose(ep);
fclose(op);
fclose(fp);
ep=fopen("efile","r");
printf("Even Number List\n");
while((no=getw(ep)!=EOF))
{
printf("%d\t",no);
}
fclose(ep);
getch();
}
Q. Write a
program to create file and store some information using fprintf() fscanf()
Ans:
#include
#include<conio.h>
#include
void main()
{
FILE *fp;
char nm[50];
int no;
clrscr();
fp=fopen("txt","w");
printf("Give Name and Roll No:");
fscanf(stdin,"%s %d",nm,&no);
fprintf(fp,"%s %d",nm,no);
fclose(fp);
fp=fopen("txt","r");
fscanf(fp,"%s %d",nm,&no);
fprintf(stdout,"%s %d",nm,no);
getch();
}
Q. Write a
program to find a percentage of vowels in accepted text. Using file.
Ans:
#include

{
FILE *fp;
char c;
clrscr();
fp=fopen("mfile","w");
printf("Give any string and press cnt-z
to terminate.\n");
while((c=getchar())!=EOF)
{
putc(c,fp);
}
fclose(fp);
fp=fopen("mfile","r");
while((c=getc(fp))!=EOF)
{
if(c=='a'||c=='u'||c=='i'||c=='o'||c=='e')
printf("%c ",c);
}
getch();
}
Q Write a
program to work as dos type command using command line arguments.
Ans:
#include
#include<conio.h>
void
main(argc ,argv)
int argc;
char *argv[];
{
FILE *fp;
int i;
int w;
clrscr();
printf(" no of command line argument
are %d\n",argc);
fp=fopen(argv[1],"w");
for(i=2;i<argc;i++)
{
fprintf(fp,"%d",argv);
}
fclose(fp);
fp=fopen(argv[1],"r");
for(i=2;i<argc;i++)
{
fscanf(fp,"%d",&w);
fprintf(stdout,"\n %s",w);
}
fclose(fp);
getch();
}
