C PROGRAM TO DISPLAY SERIES AND FIND SUM OF 1+3+5+....+n. Code: #include<stdio.h> int main() { int i,n,sum=1; printf("Enter any number n:"); scanf("%d",&n);     printf("1"); for(i=3;i<=n;i++) { printf("+ %d ",i); sum=sum+i; i++; } printf("\nSum is: %d", sum); } Explanation: First we are declaring the variables in integer datatype. Next is we are asking the user to enter a number so that we can find the sum of series and display it. We are storing the user entered data in the variable "n" . using a for loop to perform the sum of series Finally, displaying the result with the sum of series .

C PROGRAM TO FIND SUM OF SERIES Code: #include<stdio.h> int main() { int i,N; unsigned long sum; printf("Enter the value of N: "); scanf("%d",&N); sum=0; for(i=1;i<=N;i++) sum= sum+ (i*i); printf("Sum of the series is: %ld\n",sum); return 0; }  Explanation:              To find sum of series we get the required data from the user by using the statement "printf". The next step is we are storing the user given data in some variable called "N".   Then we are processing it using the above statements.  Then to get the desired output we are printing the exact statement to be displayed again using printf statement. outpu...

 C program to display the symbol "*" 20 times code: #include<stdio.h> int main() { int i, n=20; for(i=0; i<n; n--)    printf("\n*"); return 0; } note: You can also use any symbols in the place of "*".   Explanation: This is simple and easy to code and understand . The first step is to declare the variables. use a for loop to print the symbol "*" for 20 times The last step is to printf the "* one by one. Output: ...

 C program to find even numbers from 1 to 20 code: #include<stdio.h> int main() { int i,n; printf(" Even numbers from 1 to 20\n"); for(i=1; i<=20; i++) { if(i%2 == 0) { printf("%d\n",i); } } return 0; } Explanation: The first step is to declare the variables Now we are using for loop to iterate untill 20 times next we are using if statement to check the condition   For example: if i=3 then the if condition will be like "if(3%2==0)" the condition is false because 3%2 is 0.06 so the condition will not be executed   after that it becomes i=4 then "if(4%2==0)" the condition is true so...

 C program to display first 10 numbers code: #include<stdio.h> int main() { int i; printf("first 10 numbers"); for(i=1;i<=10;i++) { printf("\n%d",i); } return 0; } Explanation: Simple and easy program to understand Step 1: Declare the variable using a datatype (int, float, char) Step 2: Printing the statement to know what we are going to do. Step 3: Using a for loop to iterate it ,so that the first ten numbers get printed. Step 4: The 10 numbers should be printed so we are using printf statement to print all those "first 10 numbers" ,to printf the numbers one by one we use newline character"/n" . Output:

 C program to find profit and loss code: #include<stdio.h> int main() { int cp,sp,profit,loss; printf("enter the cost price:"); scanf("%d",&cp); printf("enter the selling price:"); scanf("%d",&sp); if(sp<cp) { /*loss*/ loss=cp-sp; printf("loss %d",loss); } else { /*profit*/     profit=sp-cp; printf("profit %d",profit); } return 0; } Explanation: Declaring the variable like "cp" for cost price "sp" for selling price and amount in integer datatype. Collecting d...

 C program to display time table code: #include<stdio.h> int main() { /*to display timetable*/ printf("Date\t|\tDate\t |\tSub1\t|\tSub2\t|\tSub3|\n13.10.21|\tMonday\t |\tTam\t|\tEng\t|\tmath|\n14.10.21|\tTuesday\t |\tVbc\t|\tDpca\t|\tCs-l|\n15.10.21|\tWednesday|\tCom\t|\tTam\t|\tEng |\n16.10.21|\tThursday |\tcs-t\t|\tDpca\t|\tVbc |\n17.10.21|\tFriday\t |\tcom\t|\tMath\t|\tEng |"); return 0; } Explanation: This program is not but displaying of timetable  with perfect alignment  In this I have used /*......*/ this is called as comment line This comment line helps in readability. Output:

 C program to find determinant of matrix code: #include <stdio.h> void main()    {   int arr1[10][10],i,j,n;   int det=0;        printf("\n\nCalculate the determinant of a 3 x 3 matrix :\n");        printf("-------------------------------------------------\n");  printf("Input elements in the first matrix :\n");        for(i=0;i<3;i++)         {             for(j=0;j<3;j++)             {            printf("element - [%d],[%d] : ",i,j);            scanf("%d",&arr1[i][j]);             }         }   printf("The matrix is :\n"); for(i=0;i<3;i++) ...

C program to find ncr code: #include <stdio.h>   int fact(int);   void main() {  int n,r,ncr;     printf("Enter a number n:");   scanf("%d",&n);     printf("Enter a number r:");   scanf("%d",&r); ncr=fact(n)/(fact(r)*fact(n-r));     printf("Value of %dC%d = %d\n",n,r,ncr); } int fact(int n) {     int i,f=1;     for(i=1;i<=n;i++)     {         f=f*i;     }     return f; } Explanation: In this program we are using "function" concept. To find ncr we first declare the variables We get the output from the user and store them. ncr formula is " ncr=fact(n)/(fact(r)*fact(n-r))" To print the result we are using printf stat...

C PROGRAM TO FIND AREA OF CIRCLE google-site-verification: google92f1512c4881b7f9.html Code: #include <stdio.h> int main() {    int area_of_circle,rad;    float PI_VALUE=3.14;    printf("Enter radius of circle: ");    scanf("%d",&rad);   area_of_circle = PI_VALUE *rad*rad;    printf("Area of circle is: %d",area_of_circle);    return(0); } Explanation: We are declaring the variable in integer data type. To find area of circle we need the value of Pi . So, we declare the value of Pi as "PI_VALUE=3.14" in float datatyp e . We getting the radius of the circle from the user. And storing the value of radius in "rad" . We declare it in float datatype because it a have value like point "...
