C programs to display Half-Pyramid/Inverted Half-Pyramid of stars and numbers

1. Write a Program in C to print half pyramid using * as shown in figure below

*

* *

* * *

* * * *

* * * * *

/*program to display the pattern*/

#include

#include

int main()

{

int m,n,num;

printf("Enter the number of rows: ");

scanf("%d",&num);

for(m=1;m<=num;++m)

{

for(n=1;n<=i;++n)

{

printf("*");

}

printf("\n");

}

return 0;

}

2. A Program in C to print inverted half pyramid using * as shown in figure    below

* * * * *

* * * *

* * *

* *

*

#include

#include

int main()

{

int m,n,num;

printf("Enter the number of rows: ");

scanf("%d",&num);

for(m=num ; m>=1 ; - -m)

{

for(n=1 ; n<=m ; ++n)

{

printf("* ");

}

printf("\n");

}

return 0;

}

3. A Program in C to print ithe following pattern.

1 2

1 2 3

1 2 3 4

1 2 3 4 5

#include

int main()

{

int m,n,rows;

printf("Enter the number of rows: ");

scanf("%d",&rows);

for(m=1;m<=rows;++m)

{

for(n=1;n<=i;++n)

{

printf("%d ",n);

}

printf("\n");

}

return 0;

}

4. A Program in C to print the following pattern.(invert half Pyramid)

1 2 3 4 5

#include

int main()

{

int m,n,rows;

printf("Enter the number of rows: ");

scanf("%d",&rows);

for(m=rows ; m>=1 ;--m)

{

for(n=1;n<=m;++n)

{

printf("%d ",n);

}

printf("\n");

}

return 0;
