Can anyone explain why am I getting an output as garbage integer?
#include<stdio.h> #include<stdlib.h> int main(){ int T; scanf("%d",&T); while(T--){ int n; scanf("%d",&n); int s[n][10]; int i,j; for(i=0;i<n;i++) { for(j=0;j<10;j++){ scanf("%d",&s[i][j]); } } for(i=0;i<n-1;i++){ for(j=0;j<10;j++){ if((s[i][j]==1)&&(s[i+1][j]==0)) s[i+1][j]=1; else if((s[i][j]==1)&&(s[i+1][j]==1)) s[i+1][j]=0; } } int cnt=0; for(j=0;j<10;j++){ cnt=cnt+s[n-1][j]; } printf("%d\n",&cnt); } return 0; }
Always read the compiler warnings 
aayush_bdn-SC31.cpp:29:27: warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘int*’ [-Wformat=]
printf("%d\n",&cnt);
okay but still I am getting a garbage value and when I write
int cnt=0;
for(j=0;j<10;j++){
if(s[n-1][j]==1)
cnt+=1;
}
I am getting output as 0. This is basically a XOR gate implimentation so can you tell me what is wrong in this approach.
Post whole code, please 
Edit: Or better still, a link to your Submission - I can’t see any from you for SC31.
#include<stdio.h> #include<stdlib.h> int main(){ int T; scanf("%d",&T); while(T--){ int n; scanf("%d",&n); int s[n][10]; int i,j; for(i=0;i<n;i++) { for(j=0;j<10;j++){ scanf("%d",&s[i][j]); } } for(i=0;i<n-1;i++){ for(j=0;j<10;j++){ if((s[i][j]==1)&&(s[i+1][j]==0)) s[i+1][j]=1; else if((s[i][j]==1)&&(s[i+1][j]==1)) s[i+1][j]=0; } } int cnt=0; for(j=0;j<10;j++){ if(s[n-1][j]==1) cnt+=1; } printf("%d\n",cnt); } return 0; }
That’s not a link to a submission - this is the link to your only submission for SC31, and it gets AC.
