    Code:
    //Ripal Bhatt
    #include <iostream>
    using namespace std;
    
    int main()
    
    {
       float month1, inch1, month2, inch2, month3, inch3;
    
       float avg;
    
       cout << "Type the first month.";
       cin >> month1;
       cout << "Type the inches of rainfall for the first month. ";
       cin >> inch1;
       cout << "Type the second month. ";
       cin >> month2;
       cout << "Type the inches of rainfall for the second month. ";
       cin >> inch2;
       cout << "Type the third month. ";
       cin >> month3;
       cout << "Type the inches of rainfall for the third month. ";
       cin >> inch3;
    
       avg = (inch1 + inch2 + inch3) / 3;
    
       cout << "The average rainfall for " << month1 << ", " << month2 << ", and " << month3 << "is " << avg << "inches.";
    
       return 0;
    }
    I'm getting "[ILINK32 Error] Error: Unresolved external '__InitVCL' referenced from C:\PROGRAM FILES (X86)\EMBARCADERO\RAD STUDIO\7.0\LIB\CP32MTI.LIB|crtlvcl" error.

    I'm trying to make it add 3 different numbers, 3 inches and find the average.

    when i run it, i get a command prompt asking, "Type the first month." And i type "April." When i press Enter i see all the things things in the quotations in my code up there.

    shouldnt it ask my to type the inches?

    you type April?
    if you want to enter strings do not use float variables


    changes

    Code:
       char month1[15],month2[15],month3[15];
       float inch1,inch2,inch3;

    Normally this error will come when we are combining more than one files. So it is your library file problem. when it is try to include in your program it gets this error.

    Type Bytes Bits Range
    short int 2 16 -16,384 -> +16,383 (16kb)
    unsigned short int 2 16 0 -> +32,767 (32Kb)
    unsigned int 4 16 0 -> +4,294,967,295 ( 4Gb)
    int 4 32 -2,147,483,648 -> +2,147,483,647 ( 2Gb)
    long int 4 32 -2,147,483,648 -> +2,147,483,647 ( 2Gb)
    signed char 1 8 -128 -> +127
    unsigned char 1 8 0 -> +255
    float 4 32
    double 8 64
    long double 12 96

    float is number but can take demical part
    double the same as float but with more digits.
    strings
    ============
    can contain letters,numbers,characters.
    "123" is a valid string(always inside quotes)
    but it is not a number.
    For example You can not add it to a number as it is.
    "123" is different from 123

    Whats a character? Like #$^&^*?
    if i type

    cout << "123";

    and if i type

    cout << 123;

    does that make any sense? how is it difference?

    you said "123" is a string and not a number... how do i add it if i ask someone to keyboard back to me a number. and if they type back 123, is that a number or a string?

    the only difference is in mathematics
    when you print "123" you get 123 on the screen
    if you print 123 you still get 123 on the screen.

    but when you say:
    "123"*123 it's wrong
    but
    123*123 is correct.

    when you want to check if two number are equal
    you say
    if (a==123){}
    but for strings
    if (strcmp(a,"123")==0){}

    when a user enter data from the keyborad
    if he enters 123 is it string or number?
    it depends on the data type of the variable you are asking.

    for example
    int a=0;
    cin>>a; //enter 123 --->it's a number

    but
    char a[30];
    cin>>a //enter 123 --->it's a string --->"123\0"
    character \0 is used to informs as that a string ends here
