Facing errors in Verifier.sol file

[junaid02012]

Hello Everyone,

This is Junaid and I have been working on incorporating ZK SNARKs within a voting application. I am facing some issues regarding the deployment of the contracts.

I am sharing the link for the repo that I have been working on.
https://github.com/Blockchain-E-Voting/EthzkSNARK-Voting/tree/master/contracts

First I am facing the issue in the 'verifier.sol' file for the switch statement. When I tried to resolve it by replacing the switch statement with if/else statement but then the compiler didn't able to identify the 'call' function and threw error 'Call' function not identified. I am using the solc (solidity compiler) version 0.4.23.
It would be great if anyone would help me in getting this application run properly.

Looking forward to your contribution.

Best Regards,
