How to open the file

ankit.singhal85 — Fri, 21 Mar 2014 03:34:46 +0530

what is the difference between fopen() and open()......similarly in putc() (or) getc() and fputc() (or ) fgetc() !!!!!!!!!!!!!

why gets() shows always warning

vikram.lamba7 — Thu, 13 Mar 2014 07:45:23 +0530

gets always shows the warning because it,s takes always more than given space so unused space is waste in gets but fgets not take more than declayred space.but if we don,t know the size of data then gets is useful and gets work after warning by default

Awesome Code for printing the individual bytes of integer ..!!!

gkarya1990 — Sun, 23 Mar 2014 01:31:56 +0530

we know in gcc the the size of int is 4 bytes and we want to print the individual bytes of it ....eg. like if we have a integer variable (unsigned int a=256) the equivalent binary representation is (00000000)(00000000)(00000001)(00000000).
code:

unsigned int a=256;
char *p=&a; int i=0;
for(i=0;i<4;i++)
printf("%d ",*(p+i));

C programming

himanshulkce — Thu, 13 Feb 2014 22:10:40 +0530

how to calculate the intersection and union of two arrays...??

how can we find the length of array by making program since there is no end character in the array??

gkarya1990 — Fri, 14 Feb 2014 00:13:08 +0530

it is easy to find the length of string since there is a null character' \0' at the end of string..but in the array of integer there is no such null characcter ..then how can we program to find the length of the integer array?????
