http://www.daniweb.com – I am a beginner with C++ so please excuse my ignorance. I am attempting to pass a dynamically created 2d array to a function. The array the [3]x[variable] array is created like this. //Create array for the transformed coords double **transf; transf = new double*[3]; for (int i=0;i<atoms;i++){ cout << i; transf[i]=new double[atoms]; }I declare the function and call it void printdata(int, string*, double* , double*,double**); int main (int argc, char **argv) { ... printdata(allatoms ,name, rot1, rot2, transf); ...}Here is the function. void printdata(int allatoms ,string* name[], double rot1[], double rot2[], double** transf[][]){ for (int i=0; i<allatoms; i++){ if (i==0){ cout << name[i]; for (int r1=0; r1<3; r1++){ printf(" %*.*f",15,8,rot1[r1] ); } cout << endl; } if (i==1){ cout << name[i]; for (int r2=0; r2<3; r2++){ printf(" %*.*f",15,8,rot2[r2] ); } cout << endl; } if (i>1){ cout << name[i]; for (int r3=0; r3<3; r3++){ printf(" %*.*f",15,8,transf[r3][i-2] ); } cout << endl; } } } When I try to compile I get rotation.cpp(225): error: parameter type involves pointer to array of unknown bound void printdata(int allatoms ,string* name[], double rot1[], double rot2[], double** transf[][]){ rotation.cpp(244): error: expression must be a pointer to a complete object type printf(" %*.*f",15,8,transf[r3][i-2] ); How can I pass this array? I would just declare the variables as global variables but the size of the array is passed in an argument to the program. (General)
