What is String
In simple words string is an array of characters.
Let's explain this
char c;
c is a character which takes only one value.
Now declare this
char c[100];
In this declaration c is an array of characters, which take upto 100 characters.
CProgram to Copy One String to Another Without Using Any Library Function
In c strcpy is used to copy the contents of one string into another. But here we copy one string contents into other string without using strcpy function.
#include <stdio.h> #include <string.h> main() { char str1[100],str2[100]; int i=0; printf("Enter string"); gets(str1); /* While string is not reach at the end*/ while(str1[i]!='\0'){ str2[i]=str1[i]; i++; } printf("string copied is %s",str2); }Output:
Enter String : Cquestions.in
String copied is : Cquestions.in
