where is the probem?

Question

int t[50];
   int i,n;
   int v,index=0;
   do {
       printf("enter n:");
       scanf("%d",&n);
   }while(n<=0||n>50);
   
    printf("reading value of t:\n");
   for(i=0;i<n;i++)
     {  printf("enter t[%d]:",i);
       scanf("%d",&t[i]);
     }
     printf("enter a value v:\n");
     scanf("%d",&v);
     
   for(i=0;i<n;i++)  
    {
        if(t[i]==v)
         index++;
     
    }
printf("number of occurence %d=%d\n",v,index);

Answer 1

Wrap your code inside,

#include<stdio.h>

int main(){

    //Your code goes here

    return 0;

}

Answer 2

Not seeing any problems? Your code below doesn't have any headers called or main declared if that's the problem?

Below is code with header and main declared, which is working successfully after tests:

#include <stdio.h>

int main(){
    
    int t[50];
    int i, n;
    int v, index = 0;
   
    do{
        printf("enter n:");
        scanf("%d",&n);
        
    }
    while (n<=0 || n>50);
    
    printf("reading value of t:\n");
   
    for(i=0;i<n;i++){  
        printf("enter t[%d]:",i);
        scanf("%d",&t[i]);
     }
     
    printf("enter a value v:\n");
    scanf("%d",&v);
     
    for(i=0;i<n;i++){
        
        if(t[i]==v)
        index++;
    }
    
    printf("number of occurence %d = %d\n", v, index);

    return 0;
}

Answer 3

#include <stdio.h>

#include <conio.h>

int main() {

int t[50];
   int i,n;
   int v,index=0;
   do {
       printf("enter n:");
       scanf("%d",&n);
   }while(n<=0||n>50);
   
    printf("reading value of t:\n");
   for(i=0;i<n;i++)
     {  printf("enter t[%d]:",i);
       scanf("%d",&t[i]);
     }
     printf("enter a value v:\n");
     scanf("%d",&v);
     
   for(i=0;i<n;i++)  
    {
        if(t[i]==v)
         index++;
     
    }
printf("number of occurence %d=%d\n",v,index);

int t[50];
   int i,n;
   int v,index=0;
   do {
       printf("enter n:");
       scanf("%d",&n);
   }while(n<=0||n>50);
   
    printf("reading value of t:\n");
   for(i=0;i<n;i++)
     {  printf("enter t[%d]:",i);
       scanf("%d",&t[i]);
     }
     printf("enter a value v:\n");
     scanf("%d",&v);
     
   for(i=0;i<n;i++)  
    {
        if(t[i]==v)
         index++;
     
    }
printf("number of occurence %d=%d\n",v,index);

return 0;

}
