appending integer to strings in a function vs concatenation

[fclopez]

I would like to concatenate strings and integers so that i produce something like this:

char *path " = "/home/myFolder%d/run%d.raw"
//where %d is a integer specifier

so that I can use it in some function

int min, max, folderNumber;
someFunction(path, min, max);

concatenating....

char fpath[256];
char fpath1[512];
char *string1 = "/home/myFolder";
char fn[6] = "/run_"
char ext[5] = ".raw";
int start =0;
int end = 10;

for (int ifolder= 0; ifolder<20; ifolder++) {
  sprintf(fpath, "%s%d", string1, ifolder);
  sprintf(fpath1, "%s%s%d%s", fpath, fn, %d, ext);

   //then call someFunction 
 someFunction(fpath1, start, end); //or
 someFunction("/home/myFolder%d/run%d.raw", 0,10);
//the point is doing sprintf(fpath1,....) causes me problems, as I want to append instead the integer variables "start" and "end"  in  someFunction(fpath1, start, end); I will be do complicated for loops in this function, hence the necessity to do append here

concatenation of strings and integers then call into a function
