Program to enter three integer and find the biggest no

Program to enter three integer and find the biggest no #include <iostream> #include <algorithm> using namespace std; int main(){ int a[3]; for ( int i = 0; i < 3; i++){ cout << "Enter Number" << endl; int b; cin >> b; a[i] = b; } cout << "Bigest No. is " << *max_element(a, a + 3) << endl; system( "pause" ); return 0; }

The Five Basic Data Types There are five atomic data types in C: character, integer, floating-point, double floating-point, and valueless (char, int, float, double, and void, respectively). As you will see, all other data types in C are based upon one of these types. The size and range of these data types may vary between processor types and compilers. However, in all cases a character is 1 byte. The size of an integer is usually the same as the word length of the execution environment of the program. For most 16-bit environments, such as DOS or Windows 3.1, an integer is 16 bits. For most 32-bit environments, such as Windows NT, an integer is 32 bits. Standard C++ does not specify a minimum size orrange for the basictypes. Instead, it simply states that they must meet certain requirements. For example, Standard C++ states that an int will “have the natural size suggested by the architecture of the execution environment." In all cases, this will meet or exceed the mini...
