C 语言实例 - 表格形式输出数据
将 1~100 的数据以 10x10 矩阵格式输出。
实例
#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;
}
#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。

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;
}

乘法运算格式。
实例
#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;
}
#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
