在 C 中打印数字模式的程序
程序说明
一个数字模式是一组基于一个规则(称为模式规则)创建的数字序列。模式规则可以使用一个或多个数学运算来描述序列中连续数字之间的关系。
模式示例
模式 1
1 2 6 3 7 10 4 8 11 13 5 9 12 14 15
模式 2
1 1 2 3 1 2 3 4 5 1 2 3 4 5 6 7 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 1 2 3 4 5 1 2 3 1
算法
Pattern 1: i stands for rows and j stands for columns. 5 stands for making pattern for 5 Rows and Columns Loop for each Row (i) K is initialized to i Loop for each Column (j) Do the Pattern for the current Column (j) Display the Value of K Reinitialize the Value of K = k + 5 - j Pattern 2: First Row: Display 1 Second Row: Display 1,2,3 Third Row: Display 1,2,3,4,5 Fourth Row: Display 1,2,3,4,5,6,7 Fifth Row: Display 1,2,3,4,5,6,7,8,9 Display the same contents from 4th Row till First Row below the fifth Row.
示例
/* Program to print Numeric Pattern */ #include<stdio.h> int main(){ int i,j,k; printf("Numeric Pattern 1"); printf("
"); printf("
"); for(i=1;i<=5;i++){ k = i; for(j=1;j<=i;j++){ printf("%d ", k); k += 5-j; } printf("
"); } printf("
"); printf("Numeric Pattern 2"); printf("
"); printf("
"); for(i = 1;i<=5;i++){ for(j = i;j<5;j++){ printf(" "); } for(k = 1;k<(i*2);k++){ printf("%d",k); } printf("
"); } for(i = 4;i>=1;i--){ for(j = 5;j>i;j--){ printf(" "); } for(k = 1;k<(i*2);k++){ printf("%d",k); } printf("
"); } getch(); return 0; }
