Difference Between C and C++: Procedural C17 vs Object-Oriented C++

Many systems programmers compare c and c++ when considering a start-up in embedded firmware, operating system kernels, or high-throughput engines. The essence of the difference between c and c++ is over programming paradigms and runtime abstractions: c is a language that is procedural, more about explicit state, structures and direct pointer manipulation, and minimal ABI surface; c++ is an extension of c with objects, destructors with RAII, templates, function overloading and exception. C has no hidden constructor calls and no name mangling, which makes it the standard for kernel interfaces and portable C ABI boundaries.

Difference Between C and C++: Paradigms, Memory & ABI Comparison — Technical Overview

#include <stdio.h>

struct Point2D {
    int x;
    int y;
};

int main(void) {
    struct Point2D p = { .x = 12, .y = 30 };
    printf("C17 designated initializer struct: (%d, %d)\n", p.x, p.y);
    return 0;
}

Runnable C example

#include <stdio.h>

struct Point2D {
    int x;
    int y;
};

int main(void) {
    struct Point2D p = { .x = 12, .y = 30 };
    printf("C17 designated initializer struct: (%d, %d)\n", p.x, p.y);
    return 0;
}
