I have worked a lot

Answer 1

Yes ans of @Yu Hao and @Bathsheba are correct.
But if you want to do the concatenation, you can go as following code snippet.

char string[]="hello";
int number=4;
char cated_string[SIZE_CATED_STRING];
sprintf(cated_string,"%s%d",string,number);
printf("%s",cated_string);

Happy Coding.
