Solution 2

well it's pretty simple.

let's store the string in an array:

C#

char str[20]="This is a test string";

and store the result in some other array:

C#

char result[10];

then use a for loop to detect when does the first "space" comes. The string of characters which comes before the first space will be the first word.

C#

for(i=0;str[i]!=" ";i++)
{
 result[i]=str[i];
}

the for loop exits when the condition str[i]!=" " becomes false.
so your result is stored in result.

Hope you understood how it worked which is more important!

At least change string to char in your arrays, as is it does not compile and is very confusing

Updated. There is nothing complex to be confused.

No more confusion between 'char' and 'string', better indeed :)

Solution 3

Try something as follows:

C#

string str = "This is a test string";

int i = str.find_first_of(' ');

string res(str.begin(), str.begin() + i);

i don't think this is possible in C++.

It is pure C++. Need to include std library header for string.

Solution 1

not sure what the C++ syntax is, but in most languages you would split the line on the space and take the first element from the resultant array.

Solution 4

hi
Have a look Here[^]

Change language tab to C++ & Copy code snippet, Change delimiter(Only space is required). Access first word from array ( i think that you want. )

Use the built-in facilities of the Standard C++ Library.
The first (blank separated) word of a std::string sentence is sentence.substr(0, sentence.find(' ')) for instance:

C++

#include <string>
std::string sentence = "It is an example sentence.";
std::string first_word = sentence.substr(0, sentence.find(' '));
