How do you write a c program to find the rank of a student read the total mark from user?

Answer 1

#include<iostream.h>

#include<conio.h>

#include<string.h>

void swap(int *,int *);

class a

{

public:

char name[20],class[20];

int roll,s1,s2,s3,total;

void input()

{

cout<<"enter name==>";

cin>>name;

cout<<"enter roll no & marks in three subjects==>";

cin>>roll>>s1>>s2>>s3;

total=s1+s2+s3;

}

void print()

{

cout<<name;

cout<<"t"<<roll<<"/t"<<total;

}

}

s[50];

void main()

{

int i,n;

clrscr();

cout<<"enter no of student==>";

cin>>n;

cout<<"enter the into==>";

for(i=0;i<n;i++)

s[i].total==s[i=1].total)

{

if(p-1==0)

cout<<"1";

else

cout<<p-1;

}

else

cout<<p;

cout<<"\n";

p++;

}

getch();}

void swap(int *a,int *b)

{

int c=*a;

*a=*b;

*b=c;

}

void sqrt(int n)

{

int p,i;

char name[20];

for(p=1;p<n;p++)

for(i=0;i<n-p;i++)

if (s[i].total<s[i+t].total)

{

strcpy(sname,s[i].name);

strcpy(s[i].name,s[i+1].name);

strcpy(s[i+1].name,name);

swap(&s[i].roll,&s[i+1].roll);

swap(&s[i].s1,&s[i+1].s1);

swap(&s[i].s2.&s[i+1].s2);

swap(&s[i].s3,&s[i+1].s3);

swap(&s[i].total & s[i+1].total);

}

}
