C++ Code Of If Else Statements 2

Any character is entered by the user; write a program to determine whether the character entered is a capital letter, a small case letter, a digit or a special symbol.The following table shows the range of ASCII values for various characters.

Characters ASCII Values

A – Z 65 – 90

a – z 97 – 122

0 – 9 48 – 57

special symbols 0 - 47, 58 - 64, 91 - 96, 123 – 127


#include<iostream.h>
#include<conio.h>

int main ()
{
 char ch;
 cout<<"Enter any character:";

  cout<<"Character is a capital letter";
 else if (ch>=97 && ch<=122)
  cout<<"Character is a small letter";
 else if (ch>=48 && ch<=57)
  cout<<"Character is a digit";

The marks obtained by a student in 5 different subjects are input by the user. The student gets a division as per the following rules:
Percentage above or equal to 60 - First division
