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;}
运行结果:
1 11 21 31 41 51 61 71 81 912 12 22 32 42 52 62 72 82 923 13 23 33 43 53 63 73 83 934 14 24 34 44 54 64 74 84 945 15 25 35 45 55 65 75 85 956 16 26 36 46 56 66 76 86 967 17 27 37 47 57 67 77 87 978 18 28 38 48 58 68 78 88 989 19 29 39 49 59 69 79 89 9910 20 30 40 50 60 70 80 90 100
等差数列输出 10x10 矩阵格式。
实例
#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:

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;}
运行结果:
3 x 1 = 33 x 2 = 63 x 3 = 93 x 4 = 123 x 5 = 153 x 6 = 183 x 7 = 213 x 8 = 243 x 9 = 273 x 10 = 30
