C

Location: examples/c/

C uses preprocessor defines (-D) to inject values:

examples/c/main.c

#include <stdio.h>

// VERSION will be set by the compiler during build
#ifndef VERSION
#define VERSION "0.0.0"
#endif

int main() {
    printf("Sample C Application\n");
    printf("Version: %s\n", VERSION);
    return 0;
}

examples/c/Makefile (excerpt)

build:
    VERSION=$$(versionator version); \
    gcc -DVERSION="\"$$VERSION\"" -o sample-app main.c

Run it

$ cd examples/c && just run
