just convert these lines of code from c language to c++

void show_record()   {system("cls"); char name[20]; float scr; FILE *f; f=fopen("score.txt","r"); fscanf(f,"%s%f",&name,&scr); printf(" \t\t*************************************************************"); printf(" \t\t %s has secured the Highest Score %0.2f",name,scr); printf(" \t\t*************************************************************"); fclose(f); getch();} void reset_score()   {system("cls");   float sc; char nm[20]; FILE *f; f=fopen("score.txt","r+"); fscanf(f,"%s%f",&nm,&sc); sc=0; fprintf(f,"%s,%.2f",nm,sc);   fclose(f);}
