C 语言：打印右三角每列相同的字母

使用 for 循环编写 C 程序，在右三角的每列打印相同的字母。或者，编写一个程序，使用 for 循环在右三角的每列打印重复的字符或相同的字母。

#include <stdio.h>

int main()
{
    int i, j, rows, alphabet = 65;
    
    printf("Enter Right Triangle Columns with Same Alphabets Rows = ");
    scanf("%d",&rows);

    printf("Right Triangle Columns with Same Alphabets Pattern\n"); 
    
	for (i = 0 ; i < rows; i++ ) 
	{
		for (j = 0 ; j <= i; j++ ) 	
		{
			printf("%c ", alphabet);
		}
		alphabet++;
		printf("\n");
	}

    return 0;
}

此 C 示例使用 while 循环显示右三角模式，其中每列重复相同的字符。

#include <stdio.h>

int main()
{
    int i = 0, j, rows, alphabet = 65;
    
    printf("Enter Right Triangle Columns with Same Alphabets Rows = ");
    scanf("%d",&rows);

    printf("\nRight Triangle Columns with Same Alphabets Pattern\n"); 
    
	while ( i < rows ) 
	{
		j = 0 ;
		while( j <= i) 	
		{
			printf("%c ", alphabet);
			j++ ;
		}
		alphabet++;
		printf("\n");
		i++;
	}

    return 0;
}

Enter Right Triangle Columns with Same Alphabets Rows = 12

使用 do while 循环打印相同字母在每个右三角行-列的 C 程序。

#include <stdio.h>

int main()
{
    int i = 0, j, rows, alphabet = 65;
    
    printf("Enter Right Triangle Columns with Same Alphabets Rows = ");
    scanf("%d",&rows);

    printf("\nRight Triangle Columns with Same Alphabets Pattern\n"); 
    
	do 
	{
		j = 0 ;
		do	
		{
			printf("%c ", alphabet);

		} while( ++j <= i);
		alphabet++;
		printf("\n");

	} while ( ++i < rows );

    return 0;
}

Enter Right Triangle Columns with Same Alphabets Rows = 15
