How to find boundary elements and higher and lower level of a matrix.

#include<stdio.h>

#include<conio.h>
void main()
{
int a[5][5],m,n,sum=0;
clrscr();
printf("Enter row :");
scanf("%d",&m);
printf("Enter coloum :");
scanf("%d",&n);
printf("Enter matrix element :\n");
for(int i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
printf("a[%d][%d]=",i,j);
scanf("%d",&a[i][j]);
}
}
printf("\nMatrix is : \n");
for(i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
printf("%d\t",a[i][j]);
}
printf("\n");
}
printf("\nBoundary element :");
for(i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
if((i*j==0)||(i==m-1)||(j==n-1))
{
printf("%d ",a[i][j]);
sum=sum+a[i][j];
}
}
}
printf("\nSum of boundary element is : %d",sum);

printf("\nHigher level : ");
sum=0;
for(i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
if(i==j)
{

printf("\t%d",a[i][j]);
sum=sum+a[i][j];
}
}

}
printf("\nSum of higher level = %d",sum);

printf("\nLower lavel : ");
sum=0;
i=m;
for(int j=0;j<n;j++)
{
i=i-1;
printf("\t%d",a[i][j]);
sum=sum+a[i][j];
}
printf("\nSum of lower level = %d",sum);
getch();
}

Thanks for sharing!

 

[Jeanh]

welcome po

 

[genji]

thanks

Sir bakit di po ma run sakin? c gamit ko
sabi 'for' loop initial declaration are only allowed in c99
no kaya problema nito?

 

[Jeanh]

try mo sa turbo c

 

[genji]

ok thanks

 

[Jeanh]

welcome po

alam ku problema jan boz. kinakailangan nang initialize ang declaration ng value variable sa c++ na latest. example.

instead:

for(int i=1; i<=10; i++)

declare variable i first:

int i;

for(i=0; i<=10; i++)

try mu

Output:

pwede na yan para sa suduko game bozz, seed random numbers nalang kulang.

opo bossing

 

[klevie_04]

java bozz magaling kah???

 

[Jeanh]

di po weh..pero may thread po ako ng java..visit mo na lang po
