Copying a string using array notation and pointer notation
#include <stdio.h>
void copy1( char *s1, const char *s2 );
void copy2( char *s1, const char *s2 );
int main()
{
char string1[ 10 ];
char *string2 = "Hello";
char string3[ 10 ];
char string4[] = "Good Bye";
copy1( string1, string2 );
printf( "string1 = %s\n", string1 );
copy2( string3, string4 );
printf( "string3 = %s\n", string3 );
return 0;
}
void copy1( char *s1, const char *s2 )
{
int i;
for ( i = 0; ( s1[ i ] = s2[ i ] ) != "\0"; i++ ) {
;
}
}
void copy2( char *s1, const char *s2 ) {
for ( ; ( *s1 = *s2 ) != "\0"; s1++, s2++ ) {
;
}
}string1 = Hello
string3 = Good Bye
Take a first name and a last name and combines the two strings
#include <string.h>
#include <stdio.h>
int main()
{
char first[100];
char last[100];
char full_name[200];
strcpy(first, "first");
strcpy(last, "last");
strcpy(full_name, first);
strcat(full_name, " ");
strcat(full_name, last);
printf("The full name is %s\n", full_name);
return (0);
}The full name is first last
