    void PosizionaNavi(){
       int Count = numeroNavi, nave = 1;
       char c_col = ' ';
       int raw = 0;
    
       printf("Insert coordinates for ship %i.\n",numeroNavi);
       while(Count>0){
            printf("Ship %u - Column: ",nave);
            scanf("%c",&c_col);
            printf("     raw: ");
            scanf("%d",&raw);
            printf("\n");
            while((c_col<'A'||c_col>'J')&&(raw<1||raw>10)){
                 printf("Invalid input, reinsert coordinates.\n");
                 printf("Ship %u - Column: ",nave);
                 scanf("%c",&c_col);
                 printf("     Raw: ");
                 scanf("%d",&raw);
                 printf("\n");
            }
            mArray[nave-1].colonna = c_col;
            mArray[nave-1].riga = raw;
            Count++;
            nave++;
        }
    }
    
    Code (markup):
    If I run this code, for the first coordinates there's no problem, but when I should insert the second, I can't insert the column.
    I know it's due to the enter key press when I insert the raw before, but I don't know how to corrct this problem.
    Could you help me?
