Main.cc: In function 'int main()':
Main.cc:4:19: error: expected initializer before 's' unsigned __int64 s=0,m=1; ^
Main.cc:11:4: error: 's' was not declared in this scope s+=m; ^
Main.cc:11:7: error: 'm' was not declared in this scope s+=m; ^
Main.cc:14:20: error: 's' was not declared in this scope printf("%I64u\n",s);
