C programmers help me-Simple program...

[senewimala1988]

Meka thama question eka mata mekata coding tika kiyanavada..Simple program 1k..arrays & loops use karanna oni...

Suppose there are 4 students each having marks of 3 subjects. Write a program to read the marks from the keyboard and calculate and display the total marks of each students. Use a 2-D array to store marks. An example would be as follows.

Enter the marks of four students, on four rows:
50 60 80
60 75 90
30 49 99
66 58 67

Total marks of four students:
190
225
178
191

Meka thama mage program eka...Eth segmentation fault kiyala enava...I am new for C programming...Help me...

#include<stdio.h>
int main()
{
int i,j;
int tot;
int a[4][3];
printf("Enter marks of four students, on four rows: \n");
for(i=0;i<4;i++);
{
tot=0;
for(j=0;i<3;j++)
{
scanf("%d",&a[j]);
tot+=a[j];
}
}
printf("Total marks of four students: \n");
for(i=0;i<4;i++)
{
printf("%d\n",tot);
}
return 0;
}

#include <stdio.h>
#include <conio.h>


void main()
{
    int marks[4][3];
    int x=0;
    int y=0;
    int total=0;

    
    for (int x=0;x<4;x++){
        for (int y=0;y<3;y++){
            printf("Enter %d Student's Marks for subject %d: ",x+1,y+1);
            scanf("%d",&marks[x][y]);
        }
    }

    printf("Student Number\t\tTotal Marks\n");
    for (x=0;x<4;x++){
        total=0;
        for (y=0;y<3;y++){
            total+=marks[x][y];                        
        }
        printf("%d\t\t\t%d\n",x+1,total);
    }
    getch();
}

hope this helps.

but maybe the input method may vary!

umbata sure neda mekaC++ nemei kiyala???
conio.h eka mokatada ban???
void main kiyala damme ai???

 

[nagaya]

void main kiyanne main eken value ekak return karanne ne NULL kiyanna

conio.h one getch(); nathnm stdio eken getchar(); use karanna

 

[senewimala1988]

void main kiyanne main eken value ekak return karanne ne NULL kiyanna

hmmm...
Value keepayaka min & max hoyanna keywords thiyenavaada???

try this edited one from crazycombo

#include <stdio.h>


int main()
{
int marks[4][3];
int total=0;
int x,y;


for ( x=0;x<4;x++){
for ( y=0;y<3;y++){
printf("Enter %d Student's Marks for subject %d: ",x+1,y+1);
scanf("%d",&marks[x][y]);
}
}

printf("Student Number\t\tTotal Marks\n");
for (x=0;x<4;x++){
total=0;
for (y=0;y<3;y++){
total+=marks[x][y];
}
printf("%d\t\t\t%d\n",x+1,total);
}
getchar();
return(0);
}

in math.h

fmax(x,y) largest value of x and y
fmin(x,y) smallest value of x and y

Thanx macho...
I will try...
