Discussion Forum : Strings - Find Output of Program (Q.No. 1)
1.
What will be the output of the program ?
#include<stdio.h>
#include<string.h>
int main()
{
char str1[20] = "Hello", str2[20] = " World";
printf("%s\n", strcpy(str2, strcat(str1, str2)));
return 0;
}
Answer: Option
Explanation:
Step 1: char str1[20] = "Hello", str2[20] = " World"; The variable str1 and str2 is declared as an array of characters and initialized with value "Hello" and " World" respectively.
Step 2: printf("%s\n", strcpy(str2, strcat(str1, str2)));
=> strcat(str1, str2)) it append the string str2 to str1. The result will be stored in str1. Therefore str1 contains "Hello World".
=> strcpy(str2, "Hello World") it copies the "Hello World" to the variable str2.
Hence it prints "Hello World".

@Vaibhav.
Because str2 is " world",not "world",there is a space before 'w'.

Why can't it be answer D. How can there be a space between the two words?
