Here is few suggestion in case of problem like this
1. Keep indent clean
2. When you start writing a tag that has both start and end add them both in the same time. Its applicable for both HTML, XML or anyother programming language.
as example
if you need to write printf("Secure");

then write printf first then write bracket both () then move your cursor in the middle and add ""

If you follow this you will never miss bracket problem.

here is an example of nice looking program

#include <stdio.h>
int main()
{
    int i,j;
    printf("choose a number : ");
    scanf("%d",&i);
    for(j=1;j<=i;j++)
    {
        printf("%d\n",j);
    }
    return 0;
}

You have an extraneous bracket before your if.
