九、程序设计 共1题 (共计30分) - 题目:主函数main()中由一组正整数组成的一维数组a为测试数据,首先找出出现次数最多的整数,若不同整数有相同的最多出现次数时,选择最早出现的整数。再判断此整数是否为阿姆斯特朗数。 阿姆斯特朗数是指,一个正整数等于其各位数字的立方和。 编写程序: 1 、编写 int maxt(int a[],int n)函数,按上述规则找出数组a中出现次数最多的正整数,函数返回此数。 2 、编写 int amst(int m)函数,判断参数m是否为阿姆斯特朗数,是阿姆斯特朗数函数返回1,否则函数返回0。 #include #include #include #include #include #define N 10 int maxt(int a[],int n) { /**********Program**********/ /********** End **********/ } int amst(int m) { /**********Program**********/ /********** End **********/ } void main() { int a[N]={370,612,153,267,153,153,267,407,407,371}; int m; FILE *fp; if((fp=fopen("data.txt","w"))==NULL) { printf("File open error\n"); exit(0); } m=maxt(a,N); if(amst(m)) { fprintf(fp,"%d is an Armstrong number.\n",m); printf("%d is an Armstrong number.\n",m); } else { fprintf(fp,"%d is not an Armstrong number.\n",m); printf("%d is not an Armstrong number.\n",m); } fclose(fp); }
