C Exercises: Create and print a specified sequence

Last update on September 19 2025 12:45:08 (UTC/GMT +8 hours)

Generate and print a sequence

Write a C program to create and print the sequence of the following example.

a=1 b=100
a=6 b=90
a=11 b=80
a=16 b=70
a=21 b=60
a=26 b=50
a=31 b=40
a=36 b=30
a=41 b=20
a=46 b=10
a=51 b=0

Sample Solution:

C Code:

#include <stdio.h>

int main ()
{
    int a, b;
    // Loop to execute statements with changing values of 'a' and 'b'
    for (a = 1, b = 100; b >= 0; a += 5, b -= 10)
        printf("a=%d \t b=%d\n", a, b);
}

Sample Output:

a=1      b=100
a=6      b=90
a=11     b=80
a=16     b=70
a=21     b=60
a=26     b=50
a=31     b=40
a=36     b=30
a=41     b=20
a=46     b=10
a=51     b=0
