In chemical compounds, subscripts indicate how many of that element are present in the compound, compared to the rest of the compound.
In MgCl2, the subscript indicates that there are two chlorine atoms for every atom of magnesium.

You test the computed or provided subscript before you use it and take action as appropriate. int somearray[100]; int i = 123; if (i < 0 i > 99) { fprintf (stderr, "Array out-of-bounds!\n") exit (1); } ... use somearray[i] ...
int linearSearch(int a[], int first, int last, int key) { // function: // Searches a[first]..a[last] for key. // returns: index of the matching element if it finds key, // otherwise -1. // parameters: // a in array of (possibly unsorted) values. // first, last in lower and upper subscript bounds // key in value to search for. // returns: // index of key, or -1 if key is not in the array. for (int i=first; i<=last; i++) { if (key == a[i]) { return i; } } return -1; // failed to find key }
Subscripts are used to identify the elements in an array, where the first element has subscript 0. Thus an array of n elements has subscripts in the range 0 to n-1. Each element may itself be an array, thus allowing multi-dimensional arrays. The subscript may be a constant or a variable. However, when declaring a static array, the subscript must be a constant. Constants include literal constants as well as named constants. A subscripted variable is simply an array or a datatype that can be divided into an array. For instance, a 32-bit int can be treated just as if it were an array of two 16-bit shorts or four 1-byte chars. Thus in the 32-bit int array, int i[10], i is a subscripted variable where i[0] is the first integer and i[9] is the last. If we then say char*c=&i, c would allow us to treat i as if it were a subscripted variable with 40 char elements (c[0] to c[39]).

An int and a char are both integral types such that a char is always guaranteed to be within the range of an int, because an int is at least as long as a short which is at least as long as a char (in bits). Converting the other way, from int to char, is not guaranteed to work, but we can guard against this by testing the int value is within the required range prior to conversion.The reason we use an int as opposed to a char in certain cases is because an int can represent values that a char cannot. This is useful in functions which would normally return a char value, but where we also need to cater for other values. Those other values could be used to indicate an error condition, for instance.

I will explain in the easiest way the difference between the function and recursive function in C language. Simple Answer is argument of the function is differ but in the recursive function it is same:) Explanation: Function int function(int,int)// function declaration main() { int n; ...... ...... n=function(a,b); } int function(int c,int d) { ...... ...... ...... } recursive Function: int recursive(int,int)// recursive Function declaration main() { int n; ..... ..... ..... ..... n=recursive(a,b); } int recursive(int a,int b) { ..... .... .... .... } Carefully see, In the recursive Function the function arguments are same.
There are five type modifiers in C++: long short signed unsigned [] - the array subscript The first four are used solely to modify the characteristics of the int type. Signed and unsigned can also be applied to the char and wchar_t types while long can also be applied to a double. If no type is specified, int is assumed. The array subscript modifier can be applied to any type including modified types and pointers to a type. Excluding arrays, pointers and the built-in bool type, C++ has the following fundamental (built-in) types: char signed char unsigned char wchar_t signed wchar_t unsigned wchar_t int signed int unsigned int short int signed short int unsigned short int long int signed long int unsigned long int long long int signed long long int unsigned long long int float double long double A plain (unmodified) char may be signed or unsigned (implementation defined) but must behave exactly as an explicitly signed or unsigned char would. However, all three are deemed separate types in C++. Similarly with wchart_t. However, an int is implicitly signed. The length of each fundamental type is implementation defined, but can be found by using the sizeof operator either upon the type itself or upon an instance of the type. The standard library <type_traits> header can be used to determine other information, particularly useful in static (compile-time) assertions. The C++ standard library also provides additional types of specific size, including int8_t, int16_t, int_32_t, int64_t, uint_8_t, uint_16_t, uint32_t and uint64_t. Note that the _t suffix is often used to denote that a type is really a typedef (an alias) for a modified type, such as size_t (an unsigned int). However wchar_t is typically implemented as a built-in type. All fundamental types can be found in <cstddef> (which is usually included when you include any standard library header such as <iostream>) while the fixed-length integers can all be found in <cstdint>.
