Q&A Discussions

The code shown below in the description runs here when I try it, but when I wrote it on code blocks it gave me 5 errors.. 1. expected imitializer before '<' token. (line 19). 2. reference to 'pair' is ambiguous. (line 26). 3. expected primary-expression before double. (line 26). 4. expected ';' before 'double'. (line 26). 5. 'obj' was not declared in this scope. (line 27). Any help please?

Can anyone help me to code this Write a method 'timesTable()' which accepts an integer value num from the keyboard and uses it to print 'times table' of itself in a structured format. Your output must include a header row. For example, if the user enters 5, your program's output should be: 5 Times Table 1 5 5 2 5 10 3 5 15 4 5 20 5 5 25 6 5 30
