while(scanf("%d",&k)==1){
c=0;
for(i=0;i<k;i++){
scanf("%d %d",&a,&b);
sum=0; c++;
for(j=a;j<=b;j++){

if(j%2==1) sum=sum+j;
else continue;

}
printf("case %d:%d\n",c,sum);
}


}
return 0;

Your output format is wrong.

And use [code]...[/code] tags to post any source code! And no "plz", please!

#include<stdio.h>
int main(){
int n,i,j,l,s,m=0,*a,*b;
scanf("%d",&n);
for(i=0;i<n;i++){
scanf("%d %d",&a,&b);}
for(i=0;i<n;i++){
s=0;
for(j=a;j<=b;j++){
if(j%2==1)
s+=j;}m++;
printf("case %d: %d\n",m,s);}
return 0;
}

You didn't allocate any memory for the pointers a and b.
Try avoiding pointers if it's not required.

#include<stdio.h>
int main(){
int a,b,i,s,n,j=1;
scanf("%d",&n);

while(j<=n){
s=0;
scanf("%d %d",&a,&b);
if((a%2)==0){


i=a+1;}
else
i=a;
while(i<=b){
s=s+i;
i=i+2;
}
printf("case %d: %d\n",j,s);
j++;

}

return 0;
}

int main(){
int n,i,j,l,s,m=0,a[100],b[100];
scanf("%d",&n);
for(i=0;i<n;i++){
scanf("%d %d",&a,&b);}
for(i=0;i<n;i++){
s=0;
for(j=a;j<=b;j++){
if(j%2==1)
s+=j;}m++;
printf("case %d: %d\n",m,s);}

return 0;
}

Case should have an uppercase C.

for(i=1;i<=n;i++)
{
scanf("%d",&a);
scanf("%d",&b);
sum=0;
for(j=a;j<=b;j++)
{

if(j%2!=0)
sum=sum+j;
}
printf("Case %d: %d\n",i,sum);


}

}

Try adding "return 0;" at the end of your code.

What's wrong with this code?
#include<stdio.h>
int main()
{
int a,b,t,n,i,j,k=1,sum;
scanf("%d",&t);
for(i=0;i<t;i++)
{
for(n=0;n<1;n++)
{
scanf("%d\n" "%d",&a,&b);
sum=0;
for(j=a;j<=b;j+=2)
{
sum=sum+j;
}
}
printf("Case %d :%d\n",k,sum);
k++;
}
return 0;
}

Why I am getting WA in this code?

#include<stdio.h>
int main()
{
int a,b,t,n,i,j,k=1,sum;
scanf("%d",&t);
for(i=0;i<t;i++)
{
for(n=0;n<1;n++)
{
scanf("%d\n" "%d",&a,&b);
sum=0;
for(j=a;j<=b;j+=2)
{
sum=sum+j;
}
}
printf("Case %d :%d\n",k,sum);
k++;
}
return 0;
}

For the sample input, the correct output is:

Code: Select all

Case 1: 9
Case 2: 8

Your output:

Code: Select all

Case 1 :9
Case 2 :8

Don't double post.
