This is a simple example of source-to-source transformation.
The objective here was to use an auxiliar struct to pass variables to a function. Then, this tries to perform the following transformation:
void func(int &a, char &c){ a=10; c='C'; } int main(){ int a; char c; func(a,c); std::cout << "a Value: " << a << c << std::endl; }typedef struct{ int a; char c; }data_t; void func(int &a, char &c){ a=10; c='C'; } int main(){ int a; char c; if(a=0) c='f'; else c='t'; data_t *d = new data_t[1]; d->a=a; d->c=c; func(d->a, d->c); std::cout << "a Value: " << d->a << d->c << std::endl; }
