# C program to print all prime numbers upto a limit(Using For Loop)

### Solution : Without using function Program/Source Code

```#include <stdio.h>

int main()
{
int n,i,z=0,limit;
printf("Enter the limit ");
scanf("%d",&limit);

for(n=2;n<=limit;n++)
{
z=0;
for(i=2;i<n;i++)
{
if(n%i==0)
{
z=1;
break;
}
}
if(z==0)
printf("%d, ",n);
}

return 0;
}
```

Output:

Enter the limit 52
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47,

# C program to print all prime numbers upto a limit(Using While Loop)

### Solution : Without using function Program/Source Code

```#include <stdio.h>

int main()
{
int n=2,i,z=0,limit;
printf("Enter the limit ");
scanf("%d",&limit);

while(n<=limit)
{
z=0;
i=2;
while(i<n)
{
if(n%i==0)
{
z=1;
break;
}
i++;
}
if(z==0)
printf("%d, ",n);
n++;
}

return 0;
}
```

Output:

Enter the limit 25
2, 3, 5, 7, 11, 13, 17, 19, 23,

# C program to print all prime numbers upto a limit

### Solution : Using function Without Passing Arguments Program/Source Code

```#include <stdio.h>
void check()
{
int n,i,z=0,limit;
printf("Enter the limit ");
scanf("%d",&limit);

for(n=2;n<=limit;n++)
{
z=0;
for(i=2;i<n;i++)
{
if(n%i==0)
{
z=1;
break;
}
}
if(z==0)
printf("%d, ",n);
}

}

int main()
{
check();
return 0;
}
```

## Output:

Enter the limit 15
2, 3, 5, 7, 11, 13,

# C program to print all prime numbers upto a limit

### Solution : Using function Passing Arguments Program/Source Code

```#include <stdio.h>
void check(int limit)
{
int n,i,z=0;
for(n=2;n<=limit;n++)
{
z=0;
for(i=2;i<n;i++)
{
if(n%i==0)
{
z=1;
break;
}
}
if(z==0)
printf("%d, ",n);
}

}

int main()
{
int limit;
printf("Enter the limit ");
scanf("%d",&limit);
check(limit);
return 0;
}
```

## Output:

Enter the limit 35
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31,
