Write the C Program in Keil Embedded C.

1. Write a program in Keil Embedded C to find factorial of a

Number.

#include

int main()

{

int a,b=1,c,d,ans1,ans2,i;

a=P0;p0=N;

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

 a=a*i;

P1=a;

}

2. Write a program to generate the sum of Fibonacci series for nTerm,

#include

int main()

{

int a,b,c,d,ans1=1,ans2;

a=P0;// P0=0

b=P1;//P1=1;

c=P2;//P2=N;

P3=0

d=0;

for(i=0;i

{

d=a+b;

a=b;

b=d;

ans1=ans1+b;

} 

P3=b;

P2=ans1;

}

3 w.a.p. to find out total prime numbers from 1 to 50 .

#include

int main()

{

int ai,j,k,cnt=0x00;

a=P0;//p0=50

for( i=2;i<=a;++i)

  {

cnt=0x00;

for( j=2;j<=i/2;++j)

{

if(i%j==0)

{

cnt++;

}

if(cnt>=1)

break;

}

if(cnt==0x00)

P1=i;

}

 

 

}
