Program Code – C++ Without Iostream: Understanding Stream Alternatives

#include <cstdio> // for printf and scanf

// Function to print out a line of text without using iostream
void printLine(const char *line) {
    printf('%s
', line);
}

// Function to read an integer from the user without using iostream
int readInteger() {
    int number;
    scanf('%d', &number);
    return number;
}

// Function to demonstrate basic file operations without using iostream
void fileOperationsExample() {
    const char *filename = 'example.txt';
    
    // Open the file for writing
    FILE *file = fopen(filename, 'w');
    if (file == nullptr) {
        printLine('Error opening file for writing.');
        return;
    }
    
    // Write to the file
    const char *textToWrite = 'Hello, file!';
    fprintf(file, '%s
', textToWrite);
    
    // Close the file
    fclose(file);
    
    // Open the file for reading
    file = fopen(filename, 'r');
    if (file == nullptr) {
        printLine('Error opening file for reading.');
        return;
    }
    
    // Read from the file
    char buffer[100];
    if (fgets(buffer, sizeof(buffer), file)) {
        printLine('Read from file:');
        printLine(buffer);
    } else {
        printLine('Error reading from file.');
    }
    
    // Close the file
    fclose(file);
}

int main() {
    // Print to console without using iostream
    printLine('Enter an integer value:');

    // Read from console without using iostream
    int value = readInteger();
    printf('You entered: %d
', value);
    
    // Demonstrate file operations without using iostream
    fileOperationsExample();
    
    return 0;
}

Code Output:

Enter an integer value:
You entered: 42
Read from file:
Hello, file!

Code Explanation:

The program covers several aspects of C++ programming without using the iostream library, which is commonly associated with input and output in C++.

1. The <cstdio> includes traditional C standard I/O functions such as printf and scanf.
2. The printLine function takes a C-style string and prints it with a newline. It uses printf for this purpose, providing a basic way to output text to the console.
3. readInteger makes use of scanf to read an integer value from the user input. This function waits for the user to enter an integer and then returns it.
4. The fileOperationsExample function demonstrates how to perform file operations. Here’s the step-by-step logic:
   • It starts by declaring a filename for an example text file.
   • It opens the file using fopen in write mode ('w'), and checks if the file was successfully opened.
   • If the file is successfully opened, it writes a string to it using fprintf.
   • It then closes the file with fclose, reopens it in read mode ('r'), and again checks for successful opening.
   • Upon successful opening for the second time, it attempts to read a string from the file into a buffer using fgets.
   • If the string is successfully read, it prints out the content of the file with printLine.
   • Finally, it closes the file once more.
5. In main, the program demonstrates the use of the previously defined functions:
   • It asks the user to enter an integer using printLine.
   • It reads the user’s input with readInteger and prints the entered value using printf.
   • It calls fileOperationsExample to demonstrate file I/O without iostream.

The architecture of the program is straightforward, making use of basic C functions and language constructs to perform I/O operations commonly handled by the iostream library in C++. Through this approach, the program achieves basic console I/O and file operations objectives.
