4. Write a program to read a text file “brijesh.txt “ count and display the number of alphanets present in it.

#include <stdio.h> #include <stdlib.h> #include <string.h> #include<conio.h> int main(void) { char str[80]; int l=0; clrscr(); FILE *fp; if((fp = fopen("brijesh.txt", "w"))==NULL) { printf("Cannot open file.\n"); exit(1); } do { printf("Enter a string :\n"); gets(str); l=strlen(str); printf("charecter lenth are\t%d\n",l); strcat(str, "\n"); /* add a newline */ fputs(str, fp); } while(*str!='\n'); return 0; }

6. Write a program to create a text file which contain some text.

#include <stdio.h> #include <stdlib.h> #include <string.h> int main(void) { char str[80]; FILE *fp; if((fp = fopen("brijesh.txt", "w"))==NULL) { printf("Cannot open file.\n"); exit(1); } do { printf("Enter a string (CR to quit):\n"); gets(str); strcat(str, "\n"); /* add a newline */ fputs(str, fp); } while(*str!='\n'); return 0; }

c program for swapping with the help of pointer

#include<stdio.h> #include<conio.h> void swap(int*,int*); void main() { int a,b; clrscr(); printf("enter two value\n"); scanf(" %d%d",&a,&b); swap(&a,&b); getch(); } void swap(int *a,int *b) { int *c; *c=*a; *a=*b; *b=*c; printf("value Are=%5d\t%d",*a,*b); }
