what is the problem in this c code?

Question

#include<stdio.h>

main()

{

int a,b,c,d;

printf("Enter the rows upto which U want to print triangle star pattern\n");

scanf("%d \n",&a);

b==a;

while(a>=0)

{

for(c=1;c<(a-1);c++)

{

printf(" ");

}

for(d=1;d<=(2*(b-a)+1);d++)

{

printf("*");

}

printf("\n");

a--;

}

return(0);

}

Answer 1

nothing ...
all code are right to print date

Answer 2

printf(" ");

you fucked up there :)

Answer 3

#include<stdio.h>

int main()

{

int a,b,c,d;

printf("Enter the rows upto which U want to print triangle star pattern\n");

scanf("%d \n",&a);

b=a;

while(a>=0)

{

for(c=1;c<(a-1);c++)

{

printf(" ");

}

for(d=1;d<=(2*(b-a)+1);d++)

{

printf("*");

}

printf("\n");

a--;

}

return(0);

}

Answer 4

#include <stdio.h>

int main()

{

int a,b,c,d;

    printf("Enter the rows upto which U want to print triangle star pattern\n");

    scanf("%d",&a);

    for(d=1; d<=a; ++d, b=0)

    {

        for(c=1; c<=a-d; ++c)

        {

            printf("  ");

        }

        while(b != 2*d-1)

        {

            printf("* ");

            ++b;

        }

        printf("\n");

    }

    

    return 0;

}

Output:

Enter the rows upto which U want to print triangle star pattern

printf("* ");
change printf(" * "); like this

Answer 5

here you used b==a

it is used in the compare case only

so here you should use just b=a

Answer 6

ALTERNATE WAY TO DO THIS:-

#include<stdio.h>

int main()

{

int row;
printf("Enter the rows upto which U want to print triangle star pattern\n");
scanf("%d \n",&row);

int t1=row;

int t2=row;

for(int i=1;i<=row;i++)

{

for(int j=1;j<=row*2-1;j++)

{

if( j<t1 && j>t2)

{

printf(" ");

}

else

{

printf("*");

}

}

t1--;

t2++;

printf("\n");

}

return 0;

}
