例如,具有此功能的打印一个大的“ A”
void printA(){
cout<<"0000000\n0 0\n0 0\n0000000\n0 0\n0 0\n";
}
0000000
0 0
0 0
0000000
0 0
0 0
我拥有所有字母,是否可以横向打印大字母?喜欢:
0000000 0000000 0000000
0 0 0 0 0 0
0 0 0 0 0 0
0000000 0000000 0000000
0 0 0 0 0 0
0 0 0 0 0 0
该程序的目标是使用垂直或水平方向这些大字母打印用户输入。
这是我程序的恢复版本:
void printA(){
cout<<"0000000\n0 0\n0 0\n0000000\n0 0\n0 0\n"<<endl;
}
void printChar(char c){
c = toupper(c);
if (c=='A')
printA();
}
int main(){
string sentence;
cout<<"enter sentence: ";
cin>> sentence;
for(unsigned int i = 0; i<sentence.length(); i++) {
char c = sentence[i];
if(c=='a')
printA();
}
return 0;
}
我用“ \ n”使字母函数保存行,另一种选择是使它们像这样:
void printA(){
cout << "0000000" << endl;
cout << "0 0" << endl;
cout << "0 0" << endl;
cout << "0000000" << endl;
cout << "0 0" << endl;
cout << "0 0" << endl;
}
如果无法以我拥有的方式将它们彼此相邻打印,我将重写它们,但是请告诉我如何以水平形式打印它们:( 谢谢!
我有以下警报:
main.cpp:29:23: warning: range-based 'for' loops only available with -std=c++11 or -std=gnu++11
for (char c : text)
^
main.cpp:31:37: warning: 'c' may be used uninitialized in this function [-Wmaybe-uninitialized]
std::cout << alphabet[c - 'A'][line] << " ";
答案 0 :(得分:3)
如果您可以像这样以其他格式(此处为2D数组)存储字符行:
const int LINES_PER_CHAR = 6;
const char* alphabet[][LINES_PER_CHAR] =
{
/* A */ { "0000000", "0 0", "0 0", "0000000", "0 0", "0 0" },
/* B */ { "000 ", "0 0", "0 0", "000 ", "0 0", "0000" }
...
};
…,那么您可以打印如下字符:
void PrintBigString(const std::string& text)
{
for (int line = 0; line < LINES_PER_CHAR; ++line)
{
for (char c : text)
{
std::cout << alphabet[c - 'A'][line] << " ";
}
std::cout << std::endl;
}
}
理想情况下,您应该添加一个健全性检查,以确保您具有字符串中当前字符的模板。
非C ++ 11编译器的变体:
void PrintBigString(const std::string& text)
{
for (int line = 0; line < LINES_PER_CHAR; ++line)
{
for (int i = 0; i < text.size(); ++i)
{
std::cout << alphabet[text[i] - 'A'][line] << " ";
}
std::cout << std::endl;
}
}
