install tcc.

downlaod Tiny C first from the homepage and then

./configure
make 
make test
sudo make install

shebang approach

after that you can use as an ‘interpreted’ language and write c ‘script’

#!/usr/local/bin/tcc -run
#include <stdio.h>
double circlarArea( double r);


int main() {
	double radius = 1.0, area = 0.0;
	area = circlarArea(radius);
	printf("        Area of Cirlces \n\n");
	printf("        Radius    area\n");
	printf("     -------------------\n");
	printf("%10.1f  %10.2f\n", radius, area);
	radius = 5.0;
	area = circlarArea(radius);
	printf("%10.1f  %10.2f\n", radius, area);
	return 0;
}



double circlarArea(double r ) {

	const double pi = 3.1415926536;
	return pi * r * r;
}

then

chmod +x circle_run.c

➜  ✗ ./circle_run.c
        Area of Cirlces

        Radius    area
     -------------------
       1.0        3.14
       5.0       78.54
➜  ✗

use ‘tcc -run’

#include <stdio.h>
double circlarArea( double r);


int main() {
	double radius = 1.0, area = 0.0;
	area = circlarArea(radius);
	printf("        Area of Cirlces \n\n");
	printf("        Radius    area\n");
	printf("     -------------------\n");
	printf("%10.1f  %10.2f\n", radius, area);
	radius = 5.0;
	area = circlarArea(radius);
	printf("%10.1f  %10.2f\n", radius, area);
	return 0;
}



double circlarArea(double r ) {

	const double pi = 3.1415926536;
	return pi * r * r;
}

save the above file as ‘circle.c’

tcc -run circle.c
➜  c_in_nutshell git:(master) ✗ tcc -run circle.c
        Area of Cirlces

        Radius    area
     -------------------
       1.0        3.14
       5.0       78.54

conclusion

I think I really like the ‘tcc -run’. really regret that I did not find it earlier. I will make learn C easier.

probably, I should be able to write a wrapper around the gcc to have the same function.
