eroor is :


1.call to undefined fn calsum() in fn main


2.fn should return a value

main()


{


int a,b,c,sum;


printf("Enter any three nos");


scanf("%d%d%d",%26amp;a,%26amp;b,%26amp;c);

return(d);


}

calsum needs a return type (probably int)
Reply:hi,the coding is correrct,but some mistakes,there are first thing have notice the function type,function returning value so,u will write datatype for its return type...ie.


#include%26lt;stdio.h%26gt;


void main()


{


int a,b,c,sum;


printf("Enter any three nos");


scanf("%d%d%d",%26amp;a,%26amp;b,%26amp;c);





sum=calsum(a,b,c);


printf("\n sum=%d",sum);


}





int calsum(x,y,z)


int x,y,z;


{


int d;


d=x+y+z;


return(d);


}


becoz the return type is int..
Reply:Your program should state the return type for the function, I have corrected it for you. Because function calsum return a value of type int therefore its method return type should also be put int.





#include%26lt;stdio.h%26gt;





void main()


{


int a,b,c,sum;


printf("Enter any three nos");


scanf("%d%d%d",%26amp;a,%26amp;b,%26amp;c);





sum=calsum(a,b,c);


printf("\n sum=%d",sum);


}





int calsum(x,y,z)


int x,y,z;


{


int d;


d=x+y+z;


return(d);


}
