From just this one line of debugging, we can presume that the word to the left of the { is either missing or not recognized in C++.
The { means "begin" and it encapsulates a group of code lines.
Of course, at the end of all the code lines to be included in that bundle we use } which means "end".
Here is quick example program of this.
Notice that the word MAIN is put in front of the { which means "begin" the MAIN function of the program.
#include <iostream.h>
int main()
{
for (int i = 32; i<128; i++)
cout << (char) i;
return 0;
}
The program instructions continue until the closing } which "ends" the function and therefore the program.
