Getting error saying: operator '==' cannot be applied to type string or char

Question

string word = Console.ReadLine();
int wordlength;
bool pass;

for(int i = 0; pass == false; ++i){
if (word[i] == " "){
// nothing happens
}
else if (word[i] == null){
pass = true;
}
else{
wordlength += 1;
}

}

Answer 1

just replace " " by ' '
when you compare the word[i] to " " you try to compare a char to a string

Answer 2

use 'single quotes' or " double quotes " when writing any string at any programming or scripting language..thats an important point for any software developer
example
a = "hello world";
b = 2345;

Answer 3

I have used .equals method in java for string n char search any such method in c#.

Answer 4

@Vincent philippe you absolute life saver. thanks a lot my man. if anybody wants the working code it looks like this:

string word = Console.ReadLine();
int wordlength = 0;

for(int i = 0; i< word.Length ++i){
if (word[i] == ' '){
// nothing happens
}
else{
wordlength += 1;
}

}

Answer 5

@Vincent philippe what do you mean? I have shortened it again because the else was not needed and it now looks like this:

string word = Console.ReadLine();
int wordlength = 0;

for(int i = 0; i< word.Length ; ++i){
if (word[i] != ' '){
++wordlength;
}
}

it still works perfectly and it's the shortest I can possibly make it myself. I have used this in a bit of code I have made if you want to check it out.

Answer 6

That didn't work. it's saying "string.this[int] is read only and can't be assigned'
so that didn't work. it also says that type char is not a nullable type so I may need to change that also.

this code may be completely wrong. I apologise in advance. I've only started learning c# 3 days ago

Answer 7

Perhaps pass could be initialized to being false. I do not know how C# handles variables that are not initialized.

Answer 8

Never delete a code, always search the mistake, else you never gonna learn and never progresse

Answer 9

first you have do remove the first if statement wich is useless and alter the else if to if

Answer 10

this is an update of your code :
string word = Console.ReadLine();
int wordlength = 0;

foreach(char c in word){
if (c != ' '){
wordlength += 1;
}
}
Console.WriteLine(wordlength);

When you don't know how many time you have to loop, you should use foreach not for
