In QBASIC, string operators allow you to manipulate and combine strings. The primary operator is the concatenation operator, which is the semicolon (;
) or the plus sign (+
). For example, you can concatenate two strings like this: result$ = "Hello" + " World"
, resulting in result$
containing "Hello World". You can also use the LEN
function to get the length of a string and the MID$
, LEFT$
, and RIGHT$
functions for extracting parts of strings.
You use the relevant formula.

In QBasic, there are several fundamental data types, including numeric types (such as INTEGER, SINGLE, and DOUBLE) for storing numbers, and STRING for text. The INTEGER type stores whole numbers, while SINGLE and DOUBLE can represent floating-point numbers with varying precision. Additionally, QBasic supports the BOOLEAN type for true/false values. Arrays can also be used to store multiple values of the same data type.
Difference between QBASIC and GWBASIC?
QBASIC keywords are reserved words that have special meanings and functions within the QBASIC programming language. They include commands like PRINT, INPUT, IF, FOR, NEXT, and END, which control the flow of the program and perform specific actions. These keywords cannot be used as variable names, as they are integral to the syntax and operation of QBASIC. Understanding these keywords is essential for writing effective QBASIC programs.
The different types of operators in QBASIC are:Arithmetic OperatorsRelational OperatorsLogical Operators
QBASIC CODE/START... ==== ...QBASIC CODE/END.
...QBASIC program code... name$="Jack" startCharPos%=2 howManyChars%=2 PRINT MID$(name$,startCharPos%,howManyChars%) ...output... ac EXPLANATION The MID$() function allows you to select characters from out of a string. In the above case the string is,... name$="Jack" ...where... J= string position 1 a= string position 2 c= string position 3 k= string position 4 ...thus, if we select MID$(name$,2,2)... ...this code is actually saying...select from the name...the character which begins at position 2 = a/and, extract 2 characters going along from there... = ac.
Yes, a string can contain operator symbols, eg: const char *s= "+*-/";
My answer to this question would be go and learn QBASIC programming language, first; as it is the 'base' language which underlies most Microsoft BASIC related programming languages, including:- Visual BASIC VBScript/Visual BASIC Script VBA/Visual BASIC for Applications VB.NET/Visual BASIC.NET -etc. QBASIC, however, doesn't use objects to do programming with...like these other languages do; and, I personally do believe this fact makes it quicker, simpler, far more straight forwards, and, easier to learn. Then, once you've already learned the QBASIC programming fundamentals, such as:- String literals/Numeric literals Variables: String, Numeric: integer/Single/Double Variable scope: Global/Local Loops: Do/Loop, For/Next If/Then/Elseif/Else/End if Select Case/End Select Logical operators/Relational Operators/Mathematical Operators Sub/End Sub,Function/End Function Filing: Serial/Binary Graphics; Text based/Drawing based/Screenmodes/Colors Sounds -etc. Then, you can consider expanding your knowledge by moving on to go study more advanced programming languages; like those already mentioned up above. Of course, it is possible to go and learn Visual BASIC without having to go learn QBASIC, first; indeed, many VB programmers have succeeding in doing things exactly that way. But, having learned QBASIC, first, myself; and, then, next, moved on to go learn Visual BASIC; I can honestly say that QBASIC certainly paved my way...thus, making learning VB feel like being a total BREEZE...! When I look back, I realise that if I had not gone and learned QBASIC, first; then, I might have had a really difficult time with struggling to go learn VB, afterwards.

It depends on what is meant by "using" - in a string or with operators; and are leading zeros allowed? The smallest positive string, with no leading zeros, is 1023456789. If a leading zero is permitted, then it is 0123456789. Once you allow operators, it depends on which operators, and the question becomes extremely complex.
In Awk, operators are used to perform various operations on data. The main types include arithmetic operators (e.g., +, -, *, /, %), relational operators (e.g., ==, !=, <, >, <=, >=), and logical operators (e.g., &&, ||, !). Additionally, there are string operators like concatenation ("string1" "string2"), and assignment operators (e.g., =, +=, -=, etc.). These operators enable effective data manipulation and processing in Awk scripts.
5k 7 3k is a string of terms: it is not an equation (or inequality) and so cannot have an answer. It is not even an expression since there are no operators between the three terms.5k 7 3k is a string of terms: it is not an equation (or inequality) and so cannot have an answer.

To stop a program from running in QBASIC, you can press "Ctrl" + "Break" on your keyboard. This interrupts the program execution and returns you to the QBASIC command prompt. Alternatively, you can close the QBASIC window to terminate the program. If you want to exit gracefully, you can also use the END statement in your code to stop execution at a specific point.
