@foskaay One of the differences between javascript and solidity is that javascript can run on web browser but solidity cannot

@foskaay Okay sie, thanks for the briefing

@foskaay

@leouloko i will check to see what is wrong with the quiz and fix if need be. Thanks for notifying me

Ok sir thank you very much

@leouloko this is now fixed.

For finding the bug and reporting it first, you just earned yourself Bug bounty of 1,000PFAQ.

Check the Earnings Page for your current balance.

CONGRATS!

@leouloko indeed you are earlier and hope you stick around well enough to be part of the great things ahead on this platform. Meanwhile, help share your experience so far on your social media etc to make more programmers or programmers to-be discover our free helpful resources.

Also, follow our official Twitter dProgrammingUniversity handle to retweet our tweets as more info about the free courses will start getting pushed out from today on social media

@leouloko try to always add the precise error you are getting so it easier to help out...

Meanwhile, just glanced through your code, I instantly spotted a serious error and have help rewrite the code below with explanation of the error i spotted personally. If that does not fix it then do let me know with precise error message along with the code

@leouloko

Your code

contract howslidityiswriten{
function helloweb3world() public view returns(string memory){

if(4-6 == 4) {
return helloweb3world;
}
else {
return alechenu is now a developer;
}

}
}

Rewriting for you below

. 

contract howSolidityIsWriten{

function helloWeb3World() public pure returns(string memory){

if(4-6 == 4) {
return "Hello Web3 World" ;
}
else {
return "Alechenu is now a Developer" ;
}

}
}

Try run above. 

@leouloko now time to point out the errors.

The most glaring that will never allow the Smart Contract to compile nor deploy at all is the you forgot to add quote signs to the string. 

Go back and rewatch the course video about intro to variable data types. 

Whenever you declare a string it must be in a single or double quote and only number does not require quotes

Example:

string number = 1; //error

 

string number = "1"; //correct 

 

string number = "one" ; //correct

 

uint number = "1"; //error 

 

uint number = 1; //correct

 

int number = -1; //correct

Others is just make your code cleaner and readable by using camel cases etc.... 

@leouloko simply ignore the spdx licensing error for now but if ready to go into production then you can use the license that fit your smart contract source code use case if it is open source like MIT or not

@leouloko Also for the screenshot you sent via live chat have you figured out the error already

I notice you have this line in the screenshot:

pragama solidity 0.8.7;

 the error is typo error, it should be:

pragma solidity 0.8.7;

//the error was "a" before "m" in the pragma which you wrote as pragama

hope that helps

@leouloko you can use the following for the license for demo use only not for production contract:
