将 1~100 的数据以 10x10 矩阵格式输出。
#include <stdio.h>int main() {int i, j, count;for(i = 1; i <= 10; i++) {for(j = i; j <=100; j += 10 )printf(" %3d", j);printf("\n");}return 0;
}
运行结果：
1 11 21 31 41 51 61 71 81 91
2 12 22 32 42 52 62 72 82 92
3 13 23 33 43 53 63 73 83 93
4 14 24 34 44 54 64 74 84 94
5 15 25 35 45 55 65 75 85 95
6 16 26 36 46 56 66 76 86 96
7 17 27 37 47 57 67 77 87 97
8 18 28 38 48 58 68 78 88 98
9 19 29 39 49 59 69 79 89 99
10 20 30 40 50 60 70 80 90 100
等差数列输出 10x10 矩阵格式。
#include <stdio.h>int main() {int i, j, count;int start, end;start = 2, end = 10;for(i = start; i <= end; i++) {count = i;for(j = 1; j <= 10; j++) {printf(" %3d", count*j);}printf("\n");}return 0;
}
运行结果：
2 4 6 8 10 12 14 16 18 20
3 6 9 12 15 18 21 24 27 30
4 8 12 16 20 24 28 32 36 40
5 10 15 20 25 30 35 40 45 50
6 12 18 24 30 36 42 48 54 60
7 14 21 28 35 42 49 56 63 70
8 16 24 32 40 48 56 64 72 80
9 18 27 36 45 54 63 72 81 90
10 20 30 40 50 60 70 80 90 100
乘法运算格式。
#include <stdio.h>int main() {int i, j, n;n = 3;j = 1;for(i = n; i <= (n*10); i+=n) {printf("%3d x %2d = %3d\n", n, j, i);j++;}return 0;
}
运行结果：
3 x 1 = 3
3 x 2 = 6
3 x 3 = 9
3 x 4 = 12
3 x 5 = 15
3 x 6 = 18
3 x 7 = 21
3 x 8 = 24
3 x 9 = 27
3 x 10 = 30
