22. Write a program to calculate average and total of 5 students for 3 subjects (use nested for loops)

#include<stdio.h>
#include<conio.h>
void main()
{
int i,j,std[5][3];
float sum[5],avg[5];
printf("Enter the marks of students:\n");
for(i=0;i<5;i++)
{
for(j=0;j<3;j++)
{
scanf("%d",&std[i][j]);
}
}
for(i=0;i<5;i++)
{
for(j=0;j<3;j++)
{
printf("%d  ",std[i][j]);
}
printf("\n");
}
for(i=0;i<5;i++)
{
for(j=0;j<3;j++)
{
sum[i]=sum[i]+std[i][j];
}
}
for(i=0;i<5;i++)
{
for(j=0;j<3;j++)
{
avg[i]=sum[i]/3;
}
}
for(i=0;i<5;i++)
{
printf("sum[%d]=%f   ",i,sum[i]);
printf("avg[%d]=%f\n",i,avg[i]);
}
getch();
}
