Help pls. Very stressed over this as its either ridiculously simple or inherent to codeblocks.

Question

Hi

So basically this is my code; (very simple) im beginner!

#include <iostream>

using namespace std;

int main ()

int num = 1;
while (num < 6)
(cout << "number: " << num << endl ;
num = num + 1);
return 0;

and these are my bugging errors;
||=== Build: Debug in Conditional2 (compiler: GNU GCC Compiler) ===|
C:\Users\Andrew\CodeBlocks\MinGW\bin\Conditional2\main.cpp|7|error: expected initializer before 'int'|
C:\Users\Andrew\CodeBlocks\MinGW\bin\Conditional2\main.cpp|8|error: expected unqualified-id before 'while'|
C:\Users\Andrew\CodeBlocks\MinGW\bin\Conditional2\main.cpp|10|error: 'num' does not name a type|
C:\Users\Andrew\CodeBlocks\MinGW\bin\Conditional2\main.cpp|11|error: expected unqualified-id before 'return'|
||=== Build failed: 4 error(s), 0 warning(s) (0 minute(s), 7 second(s)) ===|

Any help, Id be most grateful.

Thanks!!
Andrew

Answer 1

#include <iostream>
using namespace std;

int main() {

int num = 1;

while (num < 6 ){

cout<< "Number: " <<num <<endl;

++num;/*< Same as num = num+1*/
}

return 0;

}

Answer 2

if you paste my answer into playground it will work exactly how you want it.

Answer 3

Right click on your src folder in the file navigator on the left, and then 'new file' or 'new...'

Answer 4

Your code needs brackets for the main function

Answer 5

int main(){
int num;

Answer 6

Copy and paste Omar's code, don't type it yourself, because you still have bracket mistakes; you put the bracket afer 'int num = 1;' and it should be before that

Answer 7

f ing hell!!! it just worked , no change from b4 pasting omars answer. but im happy now !! mayb cos i shut down twice! luv it

Answer 8

i tried this. nothing. the main which is causing this screwy code is ; 'expected ')' before ';' token. what is this? as the rest i can fix if needed

Answer 9

#include<iostream>
using namespace std;
int main(){
int num=1;
while(num<6){
cout<<"number:"<<num<<endl;
num=num+1;}
return 0;}

Answer 10

Thanks Omar; so wot is wrong with this;

#include <iostream>

using namespace std;

int main()
int num = 1;{
while (num < 6){
cout << "number: " << num << endl;
++num;}

return 0;}

error is ;

||=== Build: Debug in Conditional2 (compiler: GNU GCC Compiler) ===|
C:\Users\Andrew\CodeBlocks\MinGW\bin\Conditional2\main.cpp|6|error: expected initializer before 'int'|
C:\Users\Andrew\CodeBlocks\MinGW\bin\Conditional2\main.cpp|6|error: expected unqualified-id before '{' token|
||=== Build failed: 2 error(s), 0 warning(s) (0 minute(s), 3 second(s)) ===|

i think you missed to declare the variable 'int' but i put that in anyway. pls check wot i got back above.

Answer 11

#include <iostream>

using namespace std;

int main(){
int num;
while (num < 6){
cout << "number: " << num << endl;
++num;}

return 0;}

||error: ld returned 1 exit status| ??.

and i get int num. BUT i thought u always had to declare at least one number to the variable which could always be overwritten anyway, but always at least one number, no?

Answer 12

int num =1;
