| friend plz help me to solve this problem plz friend solve this code for me I dont know what is the wrong with it. it is in c++ programing language. #include <stdio.h> #include <string.h> #define size 20 struct data { int age; int year; char course[6]; char name[20]; } students[20]; struct temporary //changed to struct? { int age; int year; char course[6]; char name[20]; } holder; int main() { int x,limit; int input,inputdata,showdata, sort_asc_by_age; do { //clrscr(); non portable avoid if possible puts("1..insert data"); puts("2..show data"); puts("3..show data in ascending order by age"); puts("4..show data in ascending order by year"); puts("5..show data in descending order by age"); puts("6..show data in descending order by year"); puts("9..exit"); printf("input choice:"); scanf("%d",&input); switch(input) { case 1: inputdata(); break; case 2: showdata(); break; case 3: sort_asc_by_age(); //added this case break; //added this case } }while(input!=9); getchar(); //getchar better than getch() //getch is non-portable return 0; } inputdata() int limit,x; printf("Size of structure to make? (1-20)\t"); scanf("%d",&limit); if(limit<1 || limit>size) { printf("Input Invalid!"); } else { limit=limit-1; printf("\n\n\nAge Year Course Name\n"); for(x=0; x<=limit; x++) { printf("Age:"); scanf("%d",&students[x].age); printf("Year:"); scanf("%d",&students[x].year); printf("Course:"); scanf("%s",students[x].course); //gets = bad printf("Name:"); scanf("%s",students[x].name); //gets = bad //although scanf is a lesser evil //for better a better input tutorial in c //check out dave's tutorial printf("\nNext entry\n"); } } showdata() { int limit; int x; printf("This are the items you inputted!"); printf("\nAge Year level Course Name\n"); for(x=0;x<size;x++) { printf("%d",students[x].age); printf("\t%d",students[x].year);//changed to %d (it is an integer!) printf("\t%s",students[x].course); printf("\t%s\n",students[x].name); } getchar(); //getchar better than getch() } sort_asc_by_age() { int x,y; for(x = 0; x < size; x++) for(y = 0; y < size; y++) if(students[y].age > students[y+1].age) { holder.age=students[y+1].age; holder.year=students[y+1].year; strcpy(holder.course,students[y+1].course); //changed string copy strcpy(holder.name,students[y+1].name);// changed students[y+1].age=students[y].age; students[y+1].year=students[y].year; strcpy(students[y+1].name,students[y].name);//changed strcpy(students[y+1].course,students[y].course);//changed students[y].age=holder.age; students[y].year=holder.year; strcpy(students[y].name,holder.name); //changed strcpy(students[y].course,holder.course);//changed } for(x=0;x<size;x++) { printf("%d",students[x].age); printf("\t%d",students[x].year); //%d printf("\t%s",students[x].course); printf("\t%s\n",students[x].name); } getch(); } sort_asc_by_year() { int x,y; for(x = 0; x < size; x++) for(y = 0; y < size-1; y++) if(students[y].year > students[y+1].age) { holder.age=students[y+1].age; holder.year=students[y+1].year; strcpy(holder.course,students[y+1].course); //changed strcpy(holder.name,students[y+1].name);//changed students[y+1].age=students[y].age; students[y+1].year=students[y].year; strcpy(students[y+1].name,students[y].name);//changed strcpy(students[y+1].course,students[y].course);//changed students[y].age=holder.age; students[y].year=holder.year; strcpy(students[y].name,holder.name); //changed strcpy(students[y].course,holder.course);//changed } for(x=0;x<size;x++) { printf("%d",students[x].age); printf("\t%d",students[x].year); //%d printf("\t%s",students[x].course); printf("\t%s\n",students[x].name); } getchar(); //getchar } sort__desc_by_age() { int x,y; for(x = 0; x < size; x++) for(y = 0; y < size; y++) if(students[y].age < students[y+1].age) { holder.age=students[y+1].age; holder.year=students[y+1].year; strcpy(holder.course,students[y+1].course); //changed strcpy(holder.name,students[y+1].name);//changed students[y+1].age=students[y].age; students[y+1].year=students[y].year; strcpy(students[y+1].name,students[y].name);//changed strcpy(students[y+1].course,students[y].course);//changed students[y].age=holder.age; students[y].year=holder.year; strcpy(students[y].name,holder.name); //changed strcpy(students[y].course,holder.course);//changed } for(x=0;x<size;x++) { printf("%d",students[x].age); printf("\t%d",students[x].year); //%d printf("\t%s",students[x].course); printf("\t%s\n",students[x].name); } getch(); } sort_desc_by_year() { int x,y; for(x = 0; x < size; x++) for(y = 0; y < size-1; y++) if(students[y].year < students[y+1].age) { holder.age=students[y+1].age; holder.year=students[y+1].year; strcpy(holder.course,students[y+1].course); //changed strcpy(holder.name,students[y+1].name);//changed students[y+1].age=students[y].age; students[y+1].year=students[y].year; strcpy(students[y+1].name,students[y].name);//changed strcpy(students[y+1].course,students[y].course);//changed students[y].age=holder.age; students[y].year=holder.year; strcpy(students[y].name,holder.name); //changed strcpy(students[y].course,holder.course);//changed } for(x=0;x<size;x++) { printf("%d",students[x].age); printf("\t%d",students[x].year); //%d printf("\t%s",students[x].course); printf("\t%s\n",students[x].name); } getchar(); //getchar() } |
