以下是我个人的代码： #include<stdio.h> using namespace std; struct contacts { char name[10]; int telephone; int age; }contacts[10]; void swap(char* x, char* y) { char* p; p = x; x = y; y = p; } void paixu(struct contacts *p,int m) { int k ,h; struct contacts temp;
for (k = 0; k < m - 1; k++) { for (h = k + 1; k < m; k++) { if (p[h].age < p[k].age) { temp = p[h]; p[h]= p[k]; p[k]= temp;
} } }
} int main() { int n, i; printf(“Input n:”); scanf_s("%d", &n); for (i = 0; i < n; i++) { printf("\nInput the name,age,telephone of the %d friend:", i+1);
scanf_s("%s",&contacts[i].name); scanf_s("%d%d", &contacts[i].age, &contacts[i].telephone); } paixu(contacts,n); printf(“after sorted:\n”); for (i = 0; i < n; i++) { printf("%d%d", contacts[i].age, contacts[i].telephone);
printf("%s", contacts[i].name);
}
return 0; }
