Visocrate:
Yeah what's up your question or request

greatnaija01:


I used to teach but i stopped in 2019 after the Cambridge international exams because I had other things... I will try to find anyone of my old colleagues who can help you

How soon

octaflav:
Hello guys. I'd like to connect to anyone who is teaching the above subject or vast in solving problems /tasks using Python.

Thanks

I dont agree with you
Orji may be a thief..but which court of law has pronounced him one?

Hes a dignatry..the bible says to respect such.

Jesus dined at a customs officers house...( their bribery,opression and extortion was like present day SARS) and the the "holy" people of then like you were grumbling..but he told them only the sick need a doctor, well people like you dont need one

You need to understand Gods character..hes not willing or deosnt want any one to perish, even that witch in your village.

Lastly what God counts as justice is not what man counts as justice.
God counts belief in christ as justice while oversabi like you counts forming holiness as justice..

Case study the armed robber on the cross...how did he make heaven? Just because he believed! ..

God offered salvation as a gift to man..hes not angry with man..and he doesnt look at mans so called am holy character..that being said when your saved a lot of worldlt things fail to appeal to you anymore

Some questions for you.

1) Can you program? Can you program in C (or C++)
2) Do you know what a lexical analyser does?
3) If you can program, do you actually have a C compiler and IDE installed on your system where you actively write, compile and debug programs?

I haven't touched programming in a while but I can understand what the bit of code I shared with you is doing. It takes an external file called PROGRAM.TXT and analyses the content of the file to identify tokens within the file. The tokens are identified as either constants, keyword (C language keywords) or operators (such as +, -, ÷, x). Its a very straightforward program despite its seemingly complicated look

valzey:

Don't be afraid. Its a simple program that:
Opens a file called "program.txt"
Goes through every string in the file:
If it finds an operator (+,-,/,*) it prints its an operator.
If it finds a keyword it prints it is a keyword
If it is none it prints it is an identifier.

Of a quick Google search this is what I got. And it's a bit intuitive to analeand understand it.

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<ctype.h>

 

int isKeyword(char buffer[]){


char keywords[32][10] ={"auto","break","case","char","const","continue","default", "do","double","else","enum","extern","float","for","goto", "if","int","long","register","return","short","signed", "sizeof","static","struct","switch","typedef","union", "unsigned","void","volatile","while"};

int i, flag = 0;

for(i = 0; i < 32; ++i){

if(strcmp(keywords[i], buffer) == 0){

flag = 1;

break;

}

}



return flag;

}

 

int main(){

char ch, buffer[15], operators[] = "+-*/%=";

FILE *fp;

int i,j=0;



fp = fopen("program.txt","r" ;


if(fp == NULL){

printf("error while opening the file\n" ;

exit(0);

}



while((ch = fgetc(fp)) != EOF){

   for(i = 0; i < 6; ++i){

   if(ch == operators[i])

   printf("%c is operator\n", ch) ;

   }

  

   if(isalnum(ch)){

   buffer[j++] = ch;

   }

   else if((ch == ' ' || ch == '\n') && (j != 0)){

   buffer[j] = '\0';

   j = 0;

     

   if(isKeyword(buffer) == 1)
printf("%s is keyword\n", buffer) ;

   else

   printf("%s is indentifier\n", buffer) ;

   }

  

}



fclose(fp) ;



return 0;

}

I disagree with the post above that it does nothing. The fact that it doesn't display any output given the state of the variables doesn't mean it does nothing.

The code assigns a new value to variable k, checks if the flag variable is equal to 10 (and since it doesn't, nothing is displayed) and waits for input from user to terminate the program execution

valzey:
From a functional perspective, the code does nothing.
It does some processing on some variables (i, j, k) which it never uses.
Now 'Hello All' will never be displayed because flag can never be 10.
Finally getchar() just keeps the program on till you enter a character and press enter at which the program terminates.

So it does nothing.
