Hey there im taking a intro course to c++ and we have a small assignment where we have the user input a string like:
He was 14 ten years ago. The next line should display just the numbers.
14.
Code:
int main()
{
char word[20];
int a;
cout<<"Enter a sentence with at least one number in it."<<endl;
cin.getline(word,20);
for(word[20])
{
if(!isdigit((unsigned char)word[20])>=0)
{
cout<<word<<endl;
}
}
system("PAUSE");
}
i also know i have all the appropriate includes just need to know how to get the isdigit to check the string and pull the numbers for display.
thanks ahead of time.
