Syntax and usage of strcmp(), strcat() in C.

strcmp()
• This function compares two strings (variables / constants) and returns integer value.
• The prototype of function is in header file string.h
• Syntax
int strcmp(const char*s1,const char*s2);
where s1 and s2 are two strings.
• The function compares string s2 with string s1.
• If s1s2, it returns value greater than zero.
• While comparing it compares ASCII value of symbol
• Example
a = strcmp(a1,a2);
This compares two string variables a1 and a2.
b = strcmp(“mouse”, “Mouse”);
This compares two string constants.

History Of C..

In the beginning was Charles Babbage and his Analytical Engine, a machine
he built in 1822 that could be programmed to carry out different computations.
Move forward more than 100 years, where the U.S. government in
1942 used concepts from Babbage’s engine to create the ENIAC, the first
modern computer.
Meanwhile, over at the AT&T Bell Labs, in 1972 Dennis Ritchie was working
with two languages: B (for Bell) and BCPL (Basic Combined Programming
Language). Inspired by Pascal, Mr. Ritchie developed the C programming
language.

My 1st Program...


#include
#include
void main ()
{
clrscr ();
printf ("\n\n\n\n");
printf ("\t\t\t*******Pankaj *******\n");
printf ("\t\t\t********************************\n");
printf ("\t\t\t\"Life is Good...\"\n");
printf ("\t\t\t********************************");
getch ();
}

Next Step...


#include
#include

void main ()
{
clrscr ();
printf ("\n\n\n\n\n\n\n\n");
printf ("\t\t\t --------------------------- \n\n");

printf ("\t\t\t | IGCT, Info Computers, INDIA | \n\n");
printf ("\t\t\t --------------------------- ");

getch ();

}

Hits!!!
