The line: a[i] = strtok(s,” “); sets a[i] to a pointer within the string, which you’re modifying and which may eventually have the temporary NUL characters (from strtok) removed. You may want to try: a[i] = strdup (strtok (s,” “)); instead. Let me explain further. Say we have the command (as it exists in memory): … Read more
DateTime.Today.Month has a return type of int, but you’re checking against a char value type. This check also returns true everytime as every month value is less than 12 or greater than 6 months. Rewrite this to be: int todayMonth = DateTime.Today.Month; if(todayMonth >= 6 && todayMonth <= 12) Edit: To check if the date … Read more
The main issue is you need to inherit template class this way: template<class T> class rectangle : public polygon<T> // polygon is a template, you need to make ^^^ // rectangle from a concrete polygon type 1 solved Templated polymorphism is not working [closed]
This answer about configuring the ecilpse.ini file can help you: What are the best JVM settings for Eclipse?

If you’re going to do this with fscanf, you want to use a scan set conversion, like: int a, b; char c[256]; fscanf(infile, “%d %d %[^\n]”, &a, &b, c); To scan all the lines in the file, you’d do something like: while (3 == fscanf(infile, “%d %d %[^\n]”, &a, &b, c)) process(a, b, c); fscanf … Read more
The decision as to what happens when using what address is rather complex. It depends on the processor architecture, OS and sometimes “what some software does”. The processor may not have memory protection, or address zero may indeed be “used for something” (in x86 real-mode, that DOS runs in, address zero contains the vector table, … Read more
Your functions are using passing by value, therefore, a copy is seen within the function. Please read about passing by reference void lire_tab(vector<int>& A); solved issue with std vector in c++ [closed]
Try removing ‘\n’ from the scanf, like this: scanf (“%i”,&x); Take a look at this discussion for additional info on using ‘\n’ in a scanf: Using “\n” in scanf() in C 2 solved C-Program – Taking extra entry to end program

strcmp & strncmp functions return 0 if strings are equal. You should do: if (strncmp(frase1, frase3, 4) == 0) … i.e.: char *str1 = “Example 1”; char *str2 = “Example 2”; char *str3 = “Some string”; char *str4 = “Example 1”; if (strncmp(str1, str2, 7) == 0) printf(“YES\n”); // “Example” <-> “Example” else printf(“NO\n”); if … Read more
When using if statements and you want to compare a result you should use == instead of =. With = you are assigning a value to a variable and == compares between to values. You can also not compare two things at the same time like: if (result = 70<=100) You need to check if … Read more
Simply Math.Round(24.86) This will round you value to 25. Your own logic will be decimal d = 1.5m; decimal r = d – Math.Truncate(d); if (r > 0) r = 1 – r; decimal value = d + r; solved How to get the round off value of a decimal in C# [duplicate]
Width and precision specifiers can be replaced by an *, that makes printf look for the value in the arguments. printf(“%5.3f”, M_PI); is equivalent to printf(“%*.*f”, 5, 3, M_PI); but now 5 and 3 can be replaced with expressions calculated at runtime. The rest of your exercise should be trivial. 1 solved Make table for … Read more
