The equation x2+y2=r2 represent a circle which centres at origin and radius is r. Write a program that read r from the keyboard and print the number of points with integer co-ordinate that lie on the circumference of the circle. #include<stdio.h> int main() { int x,y,r; printf("n Enter the radius:"); scanf("%d",&r); for(x=-r;x<=r;x++) { for(y=-r;y<=r;y++) […]
Write a C program to count the frequency of each vowel from a user-supplied string. #include<stdio.h> #include<string.h> int main() { char s[20],i,v=0,c=0; printf("n Enter the string: "); gets(s); puts(s); for(i=0;s[i]!=”;i++) { if((s[i]>=65 && s[i]<=91)||(s[i]>=97 && s[i]<=122)) switch(s[i]) { case ‘a’: case ‘A’: case ‘e’: case ‘E’: case ‘i’: case ‘I’: case ‘o’: case ‘O’: case
Write a program which take an integer as input and print the digits of an integer in words, after storing in a character array. [ if input : 2403 , output : Two Four Zero Three] #include<stdio.h> int main() { int num,b=0,r,temp; char *c[]={"Zero ","One ","Two ","Three ","Four ","Five ","Six ","Seven ","Eight ","Nine "}; printf("n
