We HAVE to work within Bloodshed 4.9.9.2.

Please help me.

Errors per compiler:
In function 'main'
line 9 parameter 'number1' is initilaized
line 9 parameter 'number2' is initialized
line 11 syntax error b4 sum

Well loads of problems. Lets discuss each pf the:

1. Learn to indent your code and do not insert linenumbers before each line. We dont need that, [ code ] tags does it for you. See this.

2. Now the problems with code. First one is that you havn't inserted '{' at beginning and '}' at end of main() function.

3. In sum = numberl + number2;line you have typed numberl instead of number1.

4. You have use printf() function improperly. It must be
printf("The sum is %d \n", sum);. Read This.

5. Dont use system("pause"). Although it has nothing to do with errors but try using getchar() instead. Read This.
