I am trying to make a program in which a user enters a string and i will print out the second word in the string with its size. The delimiter's are space( ), comma(,) and tab( ). I have used a character array and fgets to read from user and a character pointer that points to the first element of the array.
source code:
#include"iostream"
#include<stdio.h>
#include<string>
using namespace std;
// extract the 2nd word from a string and print it with its size(the number of characters in 2nd word)
int main()
{
char arr[30], arr1[30];
char *str = &arr1[0];
cout<<"Enter a string: ";
fgets(str, 30, stdin);
int i = 0, j, count = 1, p = 0; // count is used to find the second word
// j points to the next index where the first delimiter is found.
// p is used to store the second word found in character array 'arr'
while(*(str+i) != '\n')
{
if(*(str+i) == ' ' || *(str+i) == ',' || *(str+i) == ' ')
{
count++;
if(count == 2)
{
// stroing 2nd word in arr character array
j = i+1;
while(*(str+j) != ' ' || *(str+j) != ',' || *(str+j) != ' ')
{
arr[p] = *(str+j);
cout<<arr[p];
p++;
i++;
j++;
}
break;
}
}
i++;
}
arr[p+1] = '\0'; // insert NULL at end
i = 0;
while(arr[i] != '\0')
{
cout<<arr[i];
i++;
}
cout<<"("<<i<<")"<<endl;
return 0;
}
Help me out with this.
